It's likely that many of the fans bouncing off the walls at this show have no idea they're watching pop royalty. MC Redfoo, the bawling livewire who comprises half of LMFAO, is the son of Motown founder Berry Gordy; the other half, SkyBlu (absent due to a back injury), is his grandson. Heaven knows what Gordy would have thought of this gig, which begins with Redfoo making genital jokes and ends with him stripped to his smalls, spraying the front row with champagne.

After wondering where it all went wrong, he just might have warmed to their idiotic act. With good reason: once you accept that LMFAO's only redeeming quality is the escapism they offer. The titles of their big hits, Party Rock Anthem and Sexy and I Know It, tell you all you need to know – it's hard not to enjoy yourself. The hip-pop duo are crude by name (it stands for Laughing My Fucking Ass Off) and crude by nature, but if Redfoo evokes an image of an Afro-wigged puppy yapping for attention, he is at least funny. So are the backing dancers, who pelt the delirious front row with glowsticks and giant inflatables. Surely this has to be a parody of the party-rocking, frat-boy mentality. Hasn't it?

There's no depth to the tunes, which are pounded out by a DJ, drummer and guitarist. Beats build to frenzied crescendos and irresistible, meaningless choruses. Hair wobbling, Redfoo brays the hit I'm in Miami Bitch, then turns his attention to a tune called I Am Not a Whore, which warns us not to assume he's a "whore", just because he likes to "do it". Don't mistake that for self-analysis; as the show ends in spumes of champagne and confetti, it's obvious LMFAO are to be taken at ridiculous face-value only.
