Is Gloucester the UK's least musical city?

Do you know it's true or do you want to leap into defence mode? Dave Simpson has declared Gloucester on the Guardian website. He says, "Let's face it, it has a lovely cathedral but when the best upcoming live attractions are ghastly Scots rockers Runrig and a Genesis tribute act this is not a town steeped in rock and roll". If you have anything to say on the matter, on the Guardian, Comment is Free. Earnest Cox in particular might want to comment on this, or start litigation!
Maybe something should be mentioned about Bristol being a capital of culture whilst you are at it. Or perhaps that would be better left unsaid.
