Cher doesn't do subtle. What she does is big, in your face, old-fashioned spectacle as she descends from the rafters in a bird cage and gigantic blue wig belting out recent(ish) hit 'Woman's World' as a troupe of sexy Roman dancers gyrates across the stage. You can tell it's going to be one big party all night long.

This may well be her third farewell tour but, amazingly, at 73 Cher's voice is still strong and clear, still hitting those big notes. From neon pink flares, for the 60s section, to the basque and coattails combo for 'Welcome to Burlesque', she looks fabulous ('like a weird lady on old Star Trek' she quips early on). She's also genuinely warm and funny in her rambling intro, with stories about Studio 54, David Letterman and making The Witches of Eastwick. Ending with the killer line, 'what's your granny doing tonight?', before reappearing riding a giant pantomime elephant for 'All or Nothing', her dancers dressed as sexy extras from Aladdin.

'The Beat Goes On' and a duet of 'I Got You Babe', with a video projection of Sonny, are real highlights, and proof of Cher's place in the pop pantheon. There's probably nothing as gloriously camp as Cher covering ABBA (we get 'Waterloo', 'SOS' and 'Fernando') in a huge blonde wig and purple velour jumpsuit.

Admittedly there's some filler; Cher isn't actually on stage for some tracks, due to multiple dazzling costume changes, but there's always something to watch: dance routines, video montages, trapeze artists. And when she is on stage, it's electric.

The only minor gripe is it would have been great to have even more 60s/70s material ('Bang Bang (My Baby Shot Me Down)' is played as a rocky instrumental and no 'Gypsies, Tramps and Thieves').

It's a joyously daft, crowd pleaser of a show. 'Turn Back Time' is a powerhouse of 80s pop nonsense and closing mega-hit 'Believe' is a hands in the air cheesy banger. She's beyond human, a true phenomenon.
