"I'm not into singing. Like, I love what I do, I don't like singing. I don't enjoy it. Some people like, find a real freedom when they sing or they walk around singing all the time, or they're really good. It's the thing that I have to work so hard on. I work so hard on it that I don't enjoy it, do you know what I mean? It's not my forte and I don't feel comfortable and I always feel like I'm going to get it wrong and those kind of things, um, I mean, I was the drummer in Drive Like I Do originally. That was the original setup, and then I found George, and that was that."
