I had to join the forum to share this.
That podcast carpetbagger Alec Baldwin did a show with Billy Joel a few years ago:
http://www.wnyc.org/story/225651-billy-joel/I listened out of morbid curiosity, and heard things almost as frightening as Frankie Teardrop. Like BJ doing impersonations of Bob Dylan and Marlon Brando. Like Baldwin croaking harmonies while Joel plays deep cuts. There's some sound-collage-worthy stuff in there, if you can slog through the long stretches of boredom.
