If you like a little bit of old-Europe idealism with your musicals - an oppression-fighting hero who can belt out a tune, flash a nifty sword and swing on a rope with a flash of light and a puff of smoke, instead of some gurgling perma-tanned pin-up on a Greek island, stamp along to the Garrick for a real treat. All this and flamenco too. Call me sentimental, but gimme a hero I can admire for 'for the dangers he has passed' as Shakespeare puts it, not some man after midnight who looks as if he'd prefer a nice cup of cocoa. As in 'Mamma Mia', and there the resemblance ends, it's the chorus of women, especially Inez the gypsy Queen, who are the real backbone - that and The Gypsy Kings, wizards of guitar and violin, who remain backstage until the curtain calls. There's real dancing, too, not running along duck boards or bouncing on beds. As for literary buffs, you can pick up the Iabel Allende version from the foyer on your way out.
