An impossible question. My favorite Beatles song is usually the one I just heard. Since I just listened to "I'm So Tired" here, that's it right now :-)
This video was banned on British television, because rules about videos noy showing actors who are clearly lip-syncing. The Beatles thought this all was a joke and di not care.
Loved their music when they first came to USA, and love it still, no matter how they were evolving, their writing, technique, and performance gave the most to development of rock n' roll ever!
