"The blues, to me, is like, being very sad, very sick...or in the church, being very happy. There's two kinds of blues: there's happy blues, and there's sad blues. I don't think I ever sing the same way twice. I don't think I ever sing the same tempo. One night, it's a little bit slow, the next night, it's a little bit brighter- it's according to how I feel. I don't know- the blues is sort of a mixed-up thing. You just have to feel it. Anything I do sing, it's part of my life."
