Pin Ups, a covers album, paid tribute to the London-based bands that influenced Bowie during the mid and late '60s. The five songs featured in the show--The Pretty Things' "Rosalyn," Them's "Here Comes the Night," The Yardbirds' "I Wish You Would," The Merseys' "Sorrow" and The Who's "I Can't Explain"--are interspersed with comments from Bowie about the London music scene. Nigel Reeve, who oversees Bowie's back catalog, discovered the recording several years ago.
