Michael Barrymore impersonating a spoof rapper called Maggot under the watchful eye of firebrand George Galloway? If the recent Celebrity Big Brother scenes hadn't happened, they would be too daft even for the plot of one of Goldie Lookin Chain's goofball raps. In fact, Maggot's spell in the BB house has somehow made the band's songs seem rather tame - except, perhaps, the one about falling in love with a Bristol Zoo inhabitant.

For a band whose act sends up hip-hop while shrewdly relying on its cliches, this overlong show was remarkably professional, even slick. At their best, Goldie Lookin Chain offer surreal, sideways glances at popular culture: stuff about no-win, no-fee lawyers and bizarre monologues about "guide dogs for the dead". The rest is harmless but safe stuff about weed and breasts, with a nevertheless important role of infuriating hip-hop purists and keeping audiences of young drunkards off the streets. The Big Brother factor is referred to, but not unduly. "I'd like to thank everyone who voted for me," says Maggot, whose spliffy, madcap image may have been damaged by his emergence on BB as a decent, principled sort.

Perhaps underneath it all, Goldie Lookin Chain have been sensible boys all along. Guns Don't Kill People ("rappers do!") is funny-ish, but makes salient points about rap's perceived links to bad behaviour. In such fleeting instances, the question arises whether they could cut it as a serious group. But then one of them starts gurning and you think, well, perhaps not.
