That was a fluke. I'd recorded a lot of stuff for this record. I worked on it over a year. Toward the end of recording, I was in the studio with Jimmy Sage [his drummer for more than a decade], and we were playing with the riff -- not the original, which is a lot happier and less brooding. He was trying some different drumbeats. It was just one of those things that popped into my head in a minor key. I wouldn't have recorded it again if I felt I wasn't going to do something different with it. The album is not a rockabilly revival or '50s music. ... My music is not a museum piece in that you've got to do this way or that way.
