Was [Yer Blues] deliberately meant to be a parody of the English blues scene?
John Lennon: Well, a bit. I'm a bit self-conscious — we all were a bit self-conscious and the Beatles were super self-conscious people about parody of Americans which we do and have done. I know we developed our own style but we still in a way parodied American music... there was a self-consciousness about singing blues. We were all listening to Sleepy John Estes and all that in art school, like everybody else. But to sing it was something else.
