This Goes To 11: Spinal Tap Movie Trivia
SNL
Spinal Tap was the Saturday Night Live musical guest on a 1984 episode hosted by Barry Bostwick. During their time preparing for the performance, show producer (at that point Dick Ebersol) invited them to join the cast as regular performers. Harry Shearer and Christopher Guest accepted, but didn’t stay long. This was Shearer’s second time as a cast member, and he later said that when he was offered the part during his Spinal Tap appearance, he “hadn’t realize[d] that guests were treated better than cast members.” Guest lasted one season.
A decade later, when Lorne Michaels was back in place as SNL’s producer, Michael McKean ended up joining the show for one year.
