Hi DLM. On your 'Karl' question - you may not have quite understood what is happening here. Give it another read.

On the Buddy Holly point - yes, that's when he died. But it's also true that he was number one in the UK singles chart, three months later.

Karl (typical Nordic version of the name, isn't it usually Charles over there?) should be one of the 1959 guys. Yeah, so many twists and turns - I better hold on to my head before it spins off my shoulders..
