When you hear the term ‘rock opera’, your first thought might be of icons and iconoclasts: Ziggy Stardust, Meat Loaf, Pink Floyd. You don’t tend to think of the Member of Parliament for Sedgefield – but TONY! [The Tony Blair Rock Opera] is here to give former Prime Minister Tony Blair his very own American Idiot (but more on George W. Bush later).

Billed as Yes, Minister meets The Rocky Horror Show, TONY! is the unruly brainchild of comedian Harry Hill and songwriter Steve Brown. Directed by Peter Rowe, it follows the titular politico from cradle to grave, from his stint as a wannabe rockstar in his student days to becoming leader of the Labour party and winning a landslide victory at the 1997 election, plus the precipitous legacy of his special relationship with POTUS and ‘personality’ politics. Jack Whittle, who previously stole the show in Mischief Theatre’s Comedy About a Bank Robbery, is a pitch-perfect PM, nailing all of Blair’s mannerisms from the rictus grin to the ‘right on’ charisma that lent New Labour its groovy young poster boy.

We follow Tony through a cavalcade of larger-than-life characters, including loved-up Liverpudlian Cherie (a top-form Tori Burgess – her running joke about fox hunting is a real winner) and bumbling frenemy Gordon Brown (Phil Sealey). Through it all, Tony is dogged by the angel and devil on his shoulder: the former, a near-saintly Neil Kinnock (original cast member Martin Johnston), portrayed as a tragic Llywelyn-style hero cut down in his political prime, with a rousing ‘Do You Hear the People Sing?’-esque swan song. (We were promised a Les Mis moment, after all). As for the latter, Howard Samuels is delectably devilish as Peter Mandelson, our sinister master of ceremonies and the architect of Blair’s ascent to the big leagues.

They’re joined by an excellent three-piece band (Oli Jackson, David Guy and Harry Brent) and supported by a lively and versatile cast including Rosie Strobel as a rabble-rousing John Prescott, Sally Cheng as the adulterous Robin Cook, Emma Jay Thomas as a dance-mad Princess Di, and William Hazell, who covers all the roles in the show and gets to shine as a briefly-spied Bill Clinton and as Blair’s boyhood hero ‘Mick Jaggers’. The cast double up in roles, which brings us Sealey’s memorable turn as a Groucho Marx-inspired Saddam Hussein and Johnston as a flight jacketed Dubya puppetered by Samuels’ bewigged Dick Cheney.

The accents are broad, the comedy even broader (bordering on bad taste), and the gags fly faster than insults at the PMQs – but the show doesn’t scrimp on the harsh reality. Blair’s accountability in the 2003 invasion of Iraq, and the three other wars he oversaw during his tenure in Number 10, are on full display, even if his culpability is downplayed into naïve self-advancement. What it does nail, however, is that Blair isn’t a pop star, but a political luvvie: picking pizzazz over principles, soaking up the spotlight while the Gordon Browns of the world are made to wait in the wings.

Entertaining with flashes of brilliance, TONY! isn’t here to set the record straight: it’s here to put that record on a turntable, smash it with a comedy mallet, and dance on the debris. While the set, wigs and costumes could do with some polishing, TONY! gets away with it in the name of slapstick silliness – and its final song has moments of genuine power and poignancy, with nods to ‘Springtime for Hitler’ and Dr Strangelove. If you’re au fait with Harry Hill’s oeuvre, you’ll find the rhythm quickly, and if not, you’ll likely still be swept away in the irreverence of it all. It might not be endorsed by the real Tony Blair, but it certainly was by the audience on opening night, who couldn’t have given it a more rapturous response. The question remains, though: TONY! may have had its Mamma Mia! moment – but will you go again?

TONY! [The Tony Blair Rock Opera] is playing a limited run at the New Theatre Cardiff from Wednesday 14 – Saturday 17 June. More information and how to book tickets here.

When the RMS Titanic sunk on its maiden voyage from Southampton to New York in 1912, it became instantly one of the deadliest peacetime disasters in history. Over 1,500 passengers were lost, and more than a century later, the fate of the ‘unsinkable’ Titanic continues to captivate the world, not least in James Cameron’s multi-Academy Award winning blockbuster that swept the Oscars in 1998. So epic was the film’s success that it (almost) eclipsed an adaptation that premiered on Broadway mere months before: Titanic The Musical, which docks at Cardiff for its 10th anniversary.

With music and lyrics by Tony Award-winning Maury Yeston (Nine, Phantom) and book by Emmy- and Oscar-winner Peter Stone (1776, Woman of the Year), Titanic The Musical follows the passengers of the White Star Line’s fateful ship. Unlike its big-budget younger brother, most of the musical’s characters are based on the real-life people who experienced the tragedy first-hand, from the three working-class Irish ‘Kates’ dreaming of a better life in the new world to the old-money couple who founded Macy’s department store.

It’s an unusual premise for a musical: how could any theatrical show convey the scale of such a disaster on the stage? Titanic achieves it and then some. The original Broadway production won five Tony Awards including Best Musical, Best Score and Best Book – and its easy to see why. David Woodhead’s set is a mechanical marvel while Yeston’s songs are sprawling and lush – when performed by the 25-strong ensemble, the music positively soars. The ship might be the star, but these actors are titans.

Their skill is showcased in the epic opening number, ‘Godspeed Titanic’, in which the passengers board the grand ocean liner for the first time. In doing so, it begins with the same exhilaration with which most shows end – more impressive still, it maintains that momentum. There are exuberant moments like the song ‘Lady’s Maid’, in which the third class passengers dream of new horizons, led by the luminous Lucie-Mae Summer. There are moments of connection, as between Alastair Hill as cheery wireless officer Harold Bride and Adam Filipe as crewman Barrett, where they marvel at how technology can bridge hearts a thousand miles apart. Valda Aviks and David Delve are funny, warm and affecting as the stately older couple who refuse to part. And Barnaby Hughes is fabulous as the haughty head butler while Joseph Peacock adds a cheeky charm as the spirited bellboy.

You might not expect a show about the Titanic to have much happiness, but Director Thom Southerland brings a lovely breeziness to moments of whimsy, like when busybody Alice Beane (a charming Bree Smith) gossips about the blue bloods on board to her loving, beleaguered husband (James Darch, on fine form). Southerland moves elegantly between these moments of delight and the encroaching drama: when the iceberg looms, it does so to the eerie melody of ‘No Moon’ – it’s as unsettling a moment as approach of the shark in Jaws. All credit to musical director Ben Papworth and the fantastic orchestra.

What the show does exceptionally well is prepare you for the coming tragedy without sliding either into maudlin doom and gloom or into ‘nudge nudge wink wink’ clue-dropping. The characters’ moments of joy, love and hope are given real poignancy, especially when you realise that they are based on real-life people and their stories. So when class-defying couple Charles and Lady Caroline (Mathew McDonald and Emma Harrold) sing of getting married as soon as they reach New York, we ache for them. And when Captain Edward Smith (Graham Bickley, masterful in the role) speaks of this being his last voyage before he retires – it gains a greater resonance. So, too, does the Ozymandian epic of ‘Mr Andrews’ Vision’ in which the Titanic’s architect (Ian McLarnon, breathtaking) watches his dreams – quite literally – sink before his eyes.

It also brings new insights into a story you might think you already know. Here, the relentless greed of White Star Chairman J. Bruce Ismay (a delectably pompous Martin Allanson), who scrimped on lifeboats to make room for more higher-paying passengers, may sound horribly familiar to us in our own time. Those who have the most – money, wealth, privilege – will always be the first on the lifeboats. Titanic The Musical gives voice to those left behind.

An unsinkable cast, an unbeatable score, and an unforgettable experience, Titanic the Musical is an emotional triumph of epic proportions – and, like the fabled ship, it must be seen to be believed.

Titanic The Musical is playing at New Theatre Cardiff from 9 – 13 May
