Aerosmith frontman Steven Tyler will never forget his first meeting with Sir Paul McCartney because the former BEATLE gave him his famous thumbs-up greeting in a men's toilet. Tyler and MCCartney first met in the late 1970s when Aerosmith covered The Beatles' COME TOGETHER for the movie SGT PEPPER'S LONELY HEARTS CLUB BAND. Tyler remembers, "I was in a backstage urinal at the Hammersmith Odeon (in London). MCCartney walked in, started doing what people do in urinals. "For the record, I did not check his size out! But I'm taking this p**s that seems to be taking forever, and Paul says, 'Hey! Steven Tyler, I f**king love your music.' And he gives me the famous thumbs-up with his one free hand. Well, that snapped my stream, right there. "It turned out to be quite a night, that one. I recall fat ones being smoked and a lot of wrestling on the floor."
