We all know that Now and Then was composed by John Lennon. However, Paul McCartney took and changed it, omitted the middle eight, added a solo, played piano over Lennon's recording, and much more. And he sang almost the whole song in unison with Lennon's voice. You might say it became a McCartney song.......To take the transformation to completion, we deleted Lennon's voice from the mix, so we can fully appreciate McCartney's singing.
