I was a fan of Saturday Night Live from the beginning.
In the summer of 1975, I saw a news item stating that the Johnny Carson reruns airing on the weekend would be replaced by a live show airing late-night Saturday. The show would have sketch comedy from a rep company, young comedians, and rock music acts. Somewhere along the way, I read that the first show would have Geoge Carlin as the host, and I was getting really eager to see the first show. That show came and went, and I was hooked, and watched the show every week.

By the end of the season, Saturday Night was a cult hit, and they were doing a few extra shows that summer. One of them would have Louise Lasser as the host.
Lasser was starring in the year's other cult hit, Mary Hartman, Mary Hartman, another show I loved. So, I was primed for this episode of Saturday Night. In those days, VCRs weren't common yet (I didn't own one until 1984), so when there was a show that I was particularly interested in, I would put the microphone from my portable tape recorder up against the TV speaker, and record the show on audio tape.
I did that with the Louise Lasser show, and listened to it several times over the next few years. The show must not have been very memorable, because many years later, the only things I remembered about it were a segment where Lasser wouldn't come out of her dressing room, and a very long monologue she'd done toward the end of the show.

The Louise Lasser show had never shown up in reruns, and in the mid-'80s, I read that Lorne Michaels considered it to have been an especially bad show, and he didn't want it rerun. Still, I was curious to see it again, and when the first season of SNL was released on DVD, I finally got the chance.
And how did the show hold up after all these years? You know, it wasn't that bad. It was slow in places, especially in a long scene where Lasser delivers a monologue to a dog, and in a short film that Lasser had made. There was a scene where she wouldn't come out of her dressing room, as I'd remembered, but it wasn't very funny. The long monologue at the end of the show was mostly about her recent arrest for shoplifting, and she segued between the story of her arrest and the song "Mary, Plain As Any Name Can Be". It was pretty charming, I thought, and not deserving of the terrible reputation the segment had received in the intervening decades.

Why did Lorne Michaels hate this episode so much? I don't know, but it isn't nearly as bad as its reputation.
In any case, it was very interesting to see this episode after so many years, and after so much folklore about the episode (which only an SNL fan would really have paid attention to).
