 The episode hosted by Steve Martin (I) (qv) featured "auditions"  of new acts for the show. It was actually a dumping ground for all  of the ideas that hadnt quite formed into coherent scenes. Since  there was no "audience", the laugh track wasnt used. Instead, the  producers had a few stagehands provide the laughter. Because there  is no audience track in this episode, it is thus the only episode in  which the closing theme is audible for its entirety; in all other  episodes the closing theme is obscured by canned applause and  audience laughter.
