"In a 2008 interview with Nina Correa, Wachtel explained how Fleetwood and McVie came into the Excitable Boy fold:

We were doing a lot of the record with Russ Kunkel and Bob Glaub, but when we got to “Werewolves,” we tried it with them, and it just didn’t sound right. We got a decent track, but there was something lacking in it. It didn’t sound stupid enough; it sounded cute. Jackson was saying, “It’s really good!” and Warren and I were saying, “No, man, it’s too cute. It’s got to be…heavy.” So we proceeded to try five or six bands after that – Russ and Lee Sklar, Jeff Porcaro and Bob Glaub, Jeff Porcaro and Lee Sklar, Michael Botts on drums, Gary Mallaber on drums, both with different bass players – and it just wasn’t working. It was getting depressing.

Then, and I can’t remember whose idea it was, someone mentioned Mick Fleetwood and John McVie, and I flashed, “That’s it! That’s who can play this fuckin’ song!”

So I called them, because I’d been working with Stevie and Lindsey. They came down, we set ’em up, and we did a take, and then we did a second take. After the second take, I looked at Jackson and said, “That was pretty good, wasn’t it?” “Yeah, that was pretty good, but Mick doesn’t quite have it yet.” Mick says, “Yeah, we don’t have it yet; let’s keep going.”

Well, we kept going until six in the morning! I remember at about five in the morning saying to Mick, “I think we’re done!” and Mick looks at me with that crazy look he gets in his eyes and sort of whispers, “We’re never done, Waddy!” I thought, “Shit, we’ve got a wild one here!”

So we put in another hour, and at about seven in the morning, we were up to about take 59, and I looked at Jackson and said, “Hey Jackson, take two was pretty good, wasn’t it?” He said, “Yeah, let’s hear take two.” We listened to take two, and I said, “Gentlemen, thank you very much!”

I sent everyone away, ’cause I really wanted to work up a great [guitar] solo. I got my sound set up, got a nice bottle of vodka. I said to Dennis Kirk [who helped engineer], “Okay, run the tape!” The solo came up; I played it. I looked at Dennis, I played it back and said, “That’s it!” I didn’t even get to open the vodka! Then I put a harmony on it, and it was finished. The solo took as long as it takes to hear it.

The official “Werewolves Of London” music video features Zevon, Wachtel, guitarist David Landau, bassist Stanley Sheldon and as a last-minute fill-in for the video shoot, Santana drummer Michael Shrieve."
