Bummer, I was only thinking about him a few days ago wondering how somebody so talented had vanished so completely. Seems the booze had quite a bit to do with it. Have to dig out the LP and wind up the gramophone again.
The only Gerry Rafferty record that I own is a 45" single from 1970. He dueted with Billy Connolly under the name of The Humbledums. The song was called Shoeshine Boy, but I do not think it made it into the top 50.
