The Muso: David Bowie

A habitual cameo-nabber (and occasional lead, back in the day), Bowie turned up in David Lynch's cinematic prequel to the TV show and only served to add to the weirdness.

He's FBI Agent Phillip Jeffries, described as "long lost" mostly because he stepped off the Philadelphia field office's elevator one day and turned up in Buenos Aires seconds later.

Appropriate Lyric: "Once a time, they nearly might have been, Bones and Oogie on a silver screen, No one knew what they could do, Except for me and you, They slip away, They slip away."
