Peacock: Can you tell me about the first track, “Let ’em in?”
Paul: It was half-written with Ringo in mind actually. He asked me to write him a tune and there was that one and another one. In the end, I told him I was nicking it and he could have the other one. I just got this idea for a song about someone knocking on the door, someone ringing the bell, and then in the middle, I got into the idea of naming people, just sort of symbolic of a crowd coming in… Sister Suzie, Brother John. Who’s Brother John?
Peacock: I was wondering…
Paul: Whoever you want it to be really, Uncle Ernie? Keith Moon flashing, I suppose, but the trouble with talking about things like that is .. that’s you’ve got to make an excuse for it all after. Someone says, “What did you mean by that?” And really I don’t know. It just comes into your head. Brother Michael — that’s obvious — that’s my brother Michael! Auntie Jin — I’ve got an Auntie Jin, Brother John — that could be whoever you want.
Peacock: Do you get fun out of the thought that people are going to sit down trying to work out the meaning behind lyrics like that?
Paul: It would be great if I wasn’t the ultimate authority on it. It would be just like “Match of the Day” watching them all go around delving into who the Walrus or Brother John is. I mean, to me Brother John is John Lennon, or Linda’s got a brother called John. I suppose it’s anyone’s brother John, but to me, it’s John Lennon. But not in any weird way. It just came out like that. So rather than hide it or change it, I left it. But now, they’re going to ask me. That’s the only problem, that’s the reason it’s not so much fun as it could be because there’s always someone coming up saying “What did you mean by…” or “Linda is Venus, you’re Mars — right?” Wrong, they’re planets, remember?
Peacock: Do you ever take things out because they might be misinterpreted?
Paul: No, I don’t think I ever do that, because normally when it’s writ itself then it’s writ. I don’t really much around with it too much. It’s like most things — you do a painting and think it’s not quite right so you do it again and it’s worse. Like a record — you can go on beyond the right take, but it’s never better. No, I don’t take things out for that reason, in fact, I’d leave things in because people were going to talk about them.
