There's a great story about Brian Wilson and John Lennon.
In the early 1970s, John Lennon, Alice Cooper and a few others were having a drink at a club in L.A.. Brian Wilson suddenly appeared, tapped Alice Cooper on the shoulder and whispered, "Can you please introduce me to John Lennon?"
Alice Cooper was shocked. He couldn't believe Brian Wilson and John Lennon had never met .... that it would be
him who had the honour of introducing them.
"OK, sure," Alice Cooper said, pointing at John Lennon. "Brian, this is John Lennon. John, this is Brian Wilson."
The two shook hands and Lennon said, "Hi Brian, it's very nice to meet you. I'm a huge fan of your music. Please join us," and the two continued to chat for a bit.
After they were leaving the club,, Alice Cooper said to Lennon, "I can't believe you had never met Brian Wilson!"
John replied, "Oh, I've known him for years. He's not well, you know."
Despite Lennon having a penchant for being mean and sarcastic with people, it shows he also had a softer side.
