John Lennon (in 1980) - "Just my attempt at writing one of those three-part harmony Smokey Robinson songs. Nothing in the lyrics... just a sound and a harmony. There was a period when I thought I didn't write melodies... that Paul wrote those and I just wrote straight, shouting rock 'n roll. But of course, when I think of some of my own songs-- 'In My Life,' or some of the early stuff-- 'This Boy,' I was writing melody with the best of them."
Paul McCartney (in 1988) - "Fabulous. And we just loved singing that three-part too. We'd learned that from: (sings) 'To know know know her is to love love love her...' We learned that in my dad's house in Liverpool."
