Jack Clement, Sun Engineer: I like that song. I was at Sun when ol’ Carl [Perkins] cut that. Sam [Phillips] was running the board. I hadn’t been there all that long. But I was there and I remember that song real well. I always liked that funny chord change in it.
Ben Folds: Yeah.
Jack: What key is that it in?
Ben: It’s in E. It goes from E to a C.
Jack: It goes to C. Right.
[Ben Folds demonstrates the chord change from E to C.]
Jack: That’s an ear-grabber, you know? I do remember everybody was excited about that song and they all liked that change from E to C.
Ben: That’s basically why I wanted to play it. It was kind of unusual for that time, I think. That’s a strange … It’s weird for now. Cool chords.
Robert Sledge, standup bass player: It’s an awesome song.
Ben Folds: Yeah, it’s a great song.
[Robert Sledge demonstrates the chord change in question.]
Robert: In an interview I heard that his guitar player said, ‘Man, you can’t do that. It’s just not right.” And Carl said, “I can do it.” The guitar player said, “It’s just not right. I don’t know if I want to play that.” And he did it anyway and made history. And it just goes to show you you’ve got to take some chances.
