Pratchett, Terry Easter Egg - "Cliff" the Troll Drummer

For non-British readers. In Soul Music, when the drummer changes his name to Cliff someone makes the comment "You'll never get anywhere in the music business with a name like that". The fact is that a certain Cliff Richard is the only artist to have topped the UK charts at least once in every decade since the 1950's. He was just about the only UK 1950's pop act to survive the Beatles era and he still regularly sells out concerts(Sad, but true).
