I watched this whole video...famous and not so famous artists choosing which one they preferred, John Lennon or Paul McCartney.
More said Lennon, and that would be my first choice, but upon reflection, I'm not so sure it's the right choice. I think long after we are gone, it will be McCartney that is considered the musical genius. He may be the greatest songwriter of all time. His melodies are timeless. (The songwriter from Counting Crows agrees with that assessment in the video.)
I listened to "Let it Be" again the other day, and that is a perfect song. Absolutely perfect.
Also, just as a side note, they are using the music from "While My Guitar Gently Weeps" as the soundtrack to this video. That's a George Harrison song.
