Louise Lasser, who hosted at the end of the first season on July 24, 1976, was the first host banned by the producers. Lasser was said to be going through personal problems at the time and was often nearly incoherent throughout the broadcast. She refused to appear in any sketches unless she was in them alone, or if her only costar was Chevy Chase. This had placed an obvious burden on production, and afterwards Lorne Michaels banned her from ever hosting again.
Note: This episode was such a disappointment to producer Lorne Michaels that it was also not repeated on NBC, although it has appeared in syndication since 1981.
