To this day, it's hard to find a singer better than Lennon was, or than McCartney was and still is. I'm in awe of McCartney. He's about the only one that I'm in awe of. He can do it all. And he's never let up. He's got the gift for melody, he's got the gift for rhythm, he can play any instrument. He can scream and shout as good as anyone, and he can sing a ballad as good as anyone. And his melodies are effortless, that's what you have to be in awe of.... he's just so damn effortless. I just wish he'd quit [laughs]. Everything that comes out of his mouth is just framed in melody.
