Just in time for Spinal Tap 2: Ed Begley Jr. is our very first TMEP Show guest who actually appeared in “This Is Spinal Tap.” In Ed’s memorable scene, he shows up as Spinal Tap’s original drummer John “Stumpy” Pepys looking like Buddy Holly behind the kit — instant classic. Begley tells us about the time Harry Nilsson surprised him with a dinner invitation at John and Yoko’s place at The Dakota; smoking a J with Charles Manson; and, of course, how filming a “test scene” that actually ended up getting use in the movie led to him being enshired in Spinal Tap lore.
