Welcome to Weismann’s Follies. Dmitri Weismann himself presides and the old gang of gorgeous gals are back for one last reunion in the theatre where they showed a leg and sang their hearts out between the wars, before it’s pulled down. It’s time to reminisce (cue for a song-list of glorious pastiches) and take stock of the ravages of the years – physical and emotional. So it’s equally the cue for a range of mould-breaking Sondheim numbers that excavate the regrets and neuroses eating away at the two couples centre-stage, former showgirls Sally and Phyllis and the stage-door johnnies, Buddy and Benjamin, whom they married. The genius of Sondheim and book-writer James Goldman is to intertwine and meld these two strands, building to a climax of ‘follies’ point numbers which become the expression of all that angst and heartache, one for each of the four, surprising, distinctive, appropriate and devastatingly revealing. The haunting of all the returnees by their younger selves, the girls in their gorgeous costumes and their stage door johnnies, acting out the past and observing their future, is another stroke of genius, another layer to this rich, complex show.
