"FROM A WINDOW"
AUTHORSHIP McCartney (.6) and Lennon (.4)
Brian Epstein would come up and say Billy J. Kramer needed a new song and they would write it on the spot.
McCARTNEY: "We would just make it up. We would sit down at rehearsal and grab a couple of hours somewhere and just with a pen and a bit of paper, scribble the lyrics down." Paul McCartney: Many Years from Now
