The most thrilling revivals interrogate a classic work, while revealing its fundamental soul anew. Marianne Elliott’s female-led, 21^st-century take on George Furth and Stephen Sondheim’s 1970 musical comedy Company makes a bold, inventive statement, but somehow also suggests this is how the piece was always meant to be. 

“What drivel! What nonsense! What escapist Techicolor twaddle!” No, not a description of Wallis Giunta’s scintillating BBC Proms at Cadogan Hall recital, it’s a lyric from “What A Movie”, Leonard Bernstein’s outstanding stand-alone number from his one-act opera Trouble In Tahiti. Narrating the story of a ridiculously torrid movie the heroine has sat through, Giunta joyously inhabited its every moment and delivered it with complete theatrical assurance.

Of Sondheim’s half-dozen masterpieces, Follies is the one which sets the bar impossibly high, both for its four principals and in its typically unorthodox dramatic structure. The one-hit showstoppers from within a glittering ensemble come thick and fast in the first half – stop the show they certainly did last night – and it’s hard not to miss all that when the camera zooms in exclusively on the quarrelling quartet.

Judy Collins was one of the great folk icons of the 1960s, competing for the spotlight with Joan Baez. Where the latter was instrumental in bringing Bob Dylan to wide prominence, the former was crucial in putting Joni Mitchell and Leonard Cohen on the musical map. She was first to record their music – on Wildflowers (1967), a seminal collection arranged by Joshua Rifkin, celebrated scholar of Bach, Beatles and Scott Joplin.

The last time BBC TV headed over to West Side Story, it landed itself with a contradiction. Christopher Swann’s 1985 fly-on-the-wall documentary The Making of West Side Story – about Leonard Bernstein recording his celebrated score with a cast of opera singers – bagged the prestigious Prix Italia, but the actual material was a wildly unidiomatic misfire. The reverse was true of BBC2’s Boxing Day special West Side Stories – The Making Of A Classic.

"Children will listen," or so goes a lyric to one of the most heart-rending numbers in Into the Woods, the Stephen Sondheim/James Lapine musical that seems rarely to be long-absent from the British stage. And the great virtue of the Fiasco Theatre's approach to this of all Sondheim shows is that the company's childlike sense of play releases the abiding seriousness, even sorrow, of the piece afresh. 

Opera North’s ongoing Ring isn’t taking up much of the chorus’s time, which presumably is one of the reasons that many of its members have decamped half a mile east to collaborate with the West Yorkshire Playhouse in an eye-popping new staging of Sondheim’s Into The Woods. That opera companies can and should stage Sondheim is vindicated by this production: the musical values are superb, my only niggle being that James Holmes’s excellent pit players are hidden offstage. The tricksy ensemble numbers are dazzling, with every word and melodic line thrillingly clear.

If nothing else, Stephen Sondheim’s best-known work will put you off pies; it will put you off barbers; and it may in the end put you off Sondheim. Popular though it seems to be with planners and programmers, it’s sluggish and heavy going as drama and thin gruel as music: three hours of clever musical patter, repetitive orchestral mechanisms, and slinky variations on the “Dies irae”. When you’ve seen one throat-slitting, one human pie-bake, you’ve seen them all.

Well, here’s an oddity. You Won’t Succeed... is too fragmented for musical theatre, too bombastic for cabaret, and about as profound as a first-draft Wikipedia page. Channelling the self-referential levity of the Monty Python show from which it takes its name would certainly help, but it’s mainly played straight. And what insight into the indelible Jewish contribution to musical theatre does two and a half hours’ investment get you? Those guys…they wrote some great songs. Oy vey.
