“I did the intro riff at home," says Marker. "It was something that just popped into my head, so I ran upstairs and got it down fast with a Strat and a Line 6 Pod. Funnily enough, it sat around for a long time. Everybody was going, ‘That’s a great riff. We’ve got to use it,’ but nobody knew what to do with it.

“Butch and Shirley had worked up the verses in the context of another song, and then somebody had the idea to put them together with this riff, and it worked out great.

“The riff you hear on the record is the same one I did at home in something like five minutes. I had recorded it with the basic drumbeat, which is some dumb drum machine I had, and I e-mailed it to everybody. Then my hard drive died and I couldn’t re-create the sound, so we used the stereo mix of my guitar with the drum machine on one track. Butch had the unenviable task of trying to hide my crappy drum sound. But it all worked out.

“I really love Shirley’s vocal, the way she channels Patti Smith. The words are all hers. If we didn’t have such a great front person, none of this stuff would work. She used to – like we all did – worry about stuff and belabor things past the point where it would do anybody any good. I think she works more off the cuff now, more immediate. It gives everything a fresh feeling.”
