John Lennon played "I Saw Her Standing There" at Madison Square Garden on Thanksgiving Day, November 28, 1974, when he took the stage at an Elton John concert. It was the last song Lennon would ever perform for a paid audience. Elton released this version as the B-side of "Philadelphia Freedom" the following year. This was the only live duet ever recorded between Elton John and John Lennon, who were good friends.
The Beatles met Mia and Prudence Farrow while visiting the Maharishi Mahesh Yogi in the summer of 1967. Prudence became obsessed with the meditative process and spent almost all of her free time in meditation. The others began to worry about her, and John Lennon wrote "Dear Prudence" as a plea for her to "come out and play" with the rest of the group. She did.
While touring in Paris, Paul McCartney tumbled out of bed one morning and found the tune to "Yesterday" in his head. At first, he thought he must have heard it somewhere before. He used the working title "Scrambled Eggs" until he could figure out the lyrics.
Paul McCartney actually wrote "Got to Get You Into My Life" as an ode to Marijuana. He says, "I kind of liked marijuana and to me it seemed it was mind-expanding, literally mind-expanding. So 'Got To Get You Into My Life' is really a song about that. It's not to a person, it's actually about pot."
Things were tense when The Beatles were working on The White Album, and at one point Ringo walked out of the recording session, briefly quitting the band. During his absence, Paul McCartney played drums on several songs. When Ringo returned, there were flowers waiting for him on his drum kit.
