Yeah, I know he was in Beatlemania (it's the thing he's best-known for, by far). What I meant was that he's a musician first, and any acting he's done has been incidental and related solely to his resemblance to McCartney. My mistake about him not singing in the episode. As I said, I just skimmed it (I didn't have the stomach to sit and watch the whole thing from start to finish). At what point in the show does he sing?
