Narratively feeble, the show doesn't end so much as just stop happening, but luckily the colourful, giddying Megamix arrives shortly afterwards to provide, at last, a taste of the elusive Spice energy, and the evening ends on an undeniable high point. It's not quite enough to make up for the staggering amount of bad jokes, clichéd characters and boring developments that have come before, but it's a welcome jolt of feel-good fun, and the audience laps it up.
A no-brainer in more ways than one, Viva Forever! doesn't exactly come heartily recommended (and could have been so much better), but should you need your life Spiced up on a winter evening and don't mind sitting through a lot of nonsense in between the hits, chances are the Piccadilly is where you wannabe.
