theartsdesk MOT: Chicago, Cambridge Theatre

EastEnders' Emma Barton leads a sharp female team in a deathlessly brassy show

Chicago, in some ways, remains the great musical theatre surprise success of modern times. Bob Fosse's dissection of sex and violence in the Windy City had a respectable Broadway run back in the 1970s (898 performances in all), featuring a heavyweight cast, two of whose three stars (Gwen Verdon and Jerry Orbach) are, alas, no longer with us.Chicago, in some ways, remains the great musical theatre surprise success of modern times.

Edinburgh Fringe: Kevin Eldon/ Lovelace: A Rock Musical/ Jeremy Lion/ Susan Calman

More from the world's biggest and best arts festival

He may call it Titting About, but Kevin Eldon’s show, his first as a solo performer (at the grand age of 49), should be made compulsory viewing for young comics. For this is a man who has learned his craft, the value of good writing, of stage presence, of timing and myriad other things while putting together a lengthy CV that includes Nighty Night, I’m Alan Partridge, Fist of Fun and Brass Eye. If you have seen him in any of those, you will know he's a comedic actor of great range and restraint.

The Seckerson Tapes: Kerry Ellis Interview

Musical-theatre-diva-cum-rock-chick discusses collaborating with Brian May

Kerry Ellis amassed a legion of adoring fans when she went "green" playing Elphaba in Stephen Schwartz's smash-hit musical both in London and on Broadway. But her pre-eminence as a musical-theatre-diva-cum-rock-chick was secured earlier still when Brian May, the celebrated lead guitarist of Queen, asked her to play Meat in the Queen/ Ben Elton show We Will Rock You. May quickly recognised a symbiosis between them and their CD single Wicked in Rock sprung a rip-roaring reimagining of "Defying Gravity" with Brian May's amazing guitar riffs a key feature.

Into the Woods, Regent's Park Open Air Theatre

Taut ensembles and three star turns in Sondheim's knottiest show

Sometimes people leave you halfway through the wood. Sondheim meant that in a life-and-death kind of way, but it applied literally to this ingenious show at the autumnal August preview I attended. Some folk thought Act One’s knitting-up of polyphonic fairy-tale lines really was the happy end. Others found unseasonable damp gnawing their bones and slunk off to comforting warmth. Don’t go, I pleaded, it gets deliciously darker.

Edinburgh Fringe: Celia Pacquola/ Could It Be Forever?/ Sammy J

More from the world's biggest and best arts festival

Celia Pacquola made her Fringe debut last year after storming various comedy festivals in her native Australia with a show about her boyfriend’s infidelity and, while it was entertaining enough, it lacked a bit of oomph. But her new show packs a real emotional and comedic punch and displays a noticeable development of her writing and performing talents.

theartsdesk MOT: Les Misérables, Queen's Theatre

Celebrating 25 years, but with a bang or a whimper?

For most people a 25th anniversary is cause for celebration – a party, a dinner, maybe a few speeches. If you are musical theatre phenomenon Les Misérables however, festivities operate on an entirely different scale. London struggles to support two opera houses, yet this anniversary year will be playing host to three separate (and briefly simultaneous) productions of Boublil and Schönberg’s classic show, including an all-star, cast-of-thousands spectacular at the O2.

Sister Act, London Palladium

Whoopi dons a wimple and draws the crowds in late-summer sell-out

You can't move in London for American performers, whether it's the Yankee contingent of The Bridge Project at the Old Vic, or the presence at various addresses of Mercedes Ruehl, Jeff Goldblum, Glee star (and erstwhile Tony nominee) Jonathan Groff, and, of course, pretty well the entire cast of Hair. But incomplete though that run-down is (one mustn't forget the silvery voiced Sierra Boggess in Love Never Dies or David Hyde Pierce's stern-faced mien in La Bête), few visitors have fired up the public as has Whoopi Goldberg, at the Palladium for three weeks to boost the musical, Sister Act, on which she also gets top billing as producer. And how is the Whoopster in a wimple? The more fascinating topic is the galvanising effect that her arrival has had on the show as a whole.

Edinburgh Fringe: Tiffany Stevenson/ Fair Trade/ Gutted: A Revenger's Musical

More from the world's biggest and best arts festival

After making her Edinburgh debut last year, Tiffany Stevenson returns with another cracking show, Dictators. Ostensibly it’s about Mao, Hitler, Pol Pot, et al, but in reality she cleverly  manages to do a show about the mother-daughter relationship and our obsession with celebrity in the guise of a political theme. Mums, celebs and bastards on the same bill - it's a stroke of genius.

Stephen Sondheim at 80, Royal Albert Hall

A slick and stylish Proms spin through some of the music man's greatest hits

Everybody in the business says don’t think Sondheim is easy. I’ve seen galas where big names stumbled in under-rehearsed numbers, and last night Bryn Terfel and Maria Friedman slipped and almost fell on the same banana skins that had done for them in a hastily semi-staged Sweeney Todd. Not enough to matter, though, and they rightly brought the house down. And the show as a whole?
