Breaking Up Is Hard To Do

“There is no question that when they broke up, Paul missed John and John missed Paul. I actually think Paul would like to write material today like he used to write. But there is no one alive now that can give him that spur.... Yet, don't forget, as a twosome they wrote nearly 300 great songs. That's more than Cole Porter or Irving Berlin or Jerome Kern ever did. That's certainly more than enough for one lifetime.'' – George Martin
