From James A. Miller and Tom Shales' 2003 Live from New York: An Uncensored History of Saturday Night Live, as Told By Its Stars, Writers and Guests.
Bill Murray: I got in a fight with Chevy the night he came back to host. That was because I was the new guy, and it was sort of like it was my job to do that. It would have been too petty for someone else to do it. It's almost like I was goaded into that. You know, I think everybody was hoping for it. I did sense that. I think they resented Chevy for leaving, for one thing. They resented him for taking a big piece of the success and leaving and making his own career go. Everybody else was from the improvisational world, where you didn't make it about you. You were an ensemble, you were a company. So when he left, there was resentment about that. It was a shock. . . .
When you become famous, you've got like a year or two where you act like a real asshole. You can't help yourself. It happens to everybody. You've got like two years to pull it together -- or it's permanent.
John Landis: I've only been to SNL three times, and one time I was there, Chevy and Billy were having a huge screaming fight in the hallway, and Michael O'Donoghue and Tom Davis were holding them back, and John and Danny jumped in because Chevy and Billy were really going to come to blows. I mean, it was a huge argument. And the thing I remember about Bill Murray -- I don't know Bill Murray, but he's screaming, you know, foaming at the mouth, "Fucking Chevy," and in anger he says, "Medium talent!" And I thought, "Ooh boy, that's funny. In anger he says 'medium talent,'" That really impressed me. I went, "So, Bill Murray -- wow, who is that guy?"
Laraine Newman: It seems like there was a tension between Chevy and Billy all along during the week. I don't know why. I don't know if Chevy provoked it or not. But it culminated with Billy saying to Chevy, "Why don't you fuck your wife once in a while?"
And I don't even remember who threw the first punch, Billy or Chevy. But it was ugly. I'd never seen guys fighting like that, let alone people I knew.
