Somebody said to me, 'But the Beatles were anti-materialistic.' That's a huge myth. John and I literally used to sit down and say, 'Now, let's write a swimming pool.'

So many times, I will have people tell me what I did when I was younger. There's so much being written [about] the early Beatles period, and even pre-Beatles period. And people will say, "Oh, he did that because that, and that happened because of that." And I'll be reading and think, "Well, that didn't happen" and, "That's not why I did that." Like anyone's history, you remember what went down better than people who weren't there.

The most important ingredient to making a song work is the magic. You've got a melody, you've got words, but on the more successful songs, there's a sort of magic glow that just happens and you can feel it happening. It just makes the songs sort of roll out.

Help them to learn songs of joy, instead of burn, baby, burn.

Putting two songs together, I've always loved that trick when it works.

Ebony and ivory live together in perfect harmony, side by side on my keyboard piano, oh Lord, why don't we?

Bach was so mathematical and I liked this idea that you could have one instrument going, 'One, two, three, four', and then you have another instrument going, [double time] 'One, two, three four', and another instrument going, [doubled again] 'One, two, three, four, one, two, three, four', so you could add twos and fours and eighths, and that happens a lot in Bach.
