Pre-DJ Shadow gig, we're in the pub and Birdy is telling us a story. He was out drinking last week with some friends and they all decided to go to a club. But his pal is wearing brown shoes with white soles, so when they get to the venue, the bouncer thinks he spies a pair of trainers and denies entrance to the motley crew.
They go into a huddle and one of their number comes up with an idea: the brown-shoed reject should go round the corner, take his socks off and put them on over the shoes, in order to hide the offending white soles. So he does so, and comes back to the club.
"You're not coming in," says the bouncer, for the second time.
"Why?" asks the hapless shoe-switcher.
"Because you're wearing your socks over your shoes," says the bouncer, not unreasonably.
