The story behind how McCartney came up with the song Paperback Writer.

He told me that he had the idea for Paperback Writer while driving out to John Lennon’s house in Weybridge in the stockbroker belt for a songwriting session. McCartney: “You knew the minute you got there you’d have a cup of tea and you’d sit and write, so it was always good if you had a theme. I’d had a thought for a song and somehow it was to do with the Daily Mail so there might have been an article in the Mail that morning about people writing paperbacks.”

By the time McCartney arrived in Weybridge he had the song’s structure in his head. McCartney: “I told John I had this idea of trying to write off to a publishers to become a paperback writer, and I said I think it should be written like a letter. I took a bit of paper out and I said it should be something like ‘Dear Sir or Madam, as the case may be…’ and I proceeded to write it just like a letter in front of him, occasionally rhyming it. And John, as I recall, just sat there and said: ‘Oh that’s it’, ‘Uhuh’, ‘Yeah’. I remember him, his amused smile, saying ‘Yes, that’s it, yes.’ You know, if it ain’t broke don’t fix it. ‘That’ll do’. Quite a nice moment. ‘Hmm, I’ve done right! I’ve done well!’ And then we went upstairs and put the melody to it. John and I sat down and finished it all up. I had no music, but it’s just a little bluesy song, not a lot of melody. Then I had the idea to do the harmonies and we arranged that in the studio.” It was the first Beatles single that was not a love song.
