Saucy Jack: David’s rock musical based on the life of Jack the Ripper. It opened and closed in London in record time. "Saucy Jack, you’re a naughty one/Saucy Jack, you’re a haughty one." Conceived by David and Derek at the Luton Palace and discussed during end-of-tour party during filming of "This is Spinal Tap." In 1996, David reported that "Saucy Jack has been workshopped within an inch of its life." Derek: "Its destiny is to be a work-in-progress." (AOL)
