Back in the '90's, the band I was in decided that we should all wear these strange garish trousers that looked akin to a pair of pyjama bottoms, this stagewear lasted two gigs till a young indie band that we were playing on a bill with took the piss so we went "back to black" so to speak, lol!
And recently I have taken to putting my mascot, Floyd Pepper (from the Muppet band of course!) on top of my amp!
