Brown's figure is characterised by a clown-like stage costume: flying helmet and goggles, a multicoloured patchwork jacket and trousers, a white shirt, a red bow tie and moccasin slippers. "You fat bastard!" is usually shouted repeatedly by his audience on his typical stand-up show to which he dances and when he approaches the microphone, he will either say "Fuck off!" or "How Did You Know It Was Fucking Me!". Brown released a film called U.F.O starring himself as Roger Lloyd Pack abducted by aliens while staying in a hotel in Blackpool during his live shows.
One of his best known songs is a cover version of "Living Next Door to Alice" recorded with Smokie titled "Living Next Door to Alice (Who the Fuck is Alice?)". He released a solo single called "A Rocking Good Christmas" (1996) and also released two albums, Take Fat and Party (1995) and Fat Out of Hell (1996).
