You are invited to the Mercury Music Prize. Dress: tux. Behaviour: rock and roll. Nick Coleman is thrilled to bits

THIS YEAR'S identity branding of choice is the luminescent hospital wrist-tag you can't get off. It has supplanted the dangly laminate as the ligger/consumer's badge of honour. If you went to the Rolling Stones' "secret" Brixton gig you got a yellow hospital wrist-tag, which the committed ligger/consumer could then accidentally forget to remove for days afterwards, letting it slip casually from under his cuffs on tube trains as a token of social prestige.
