Aerosmith frontman Steven Tyler will never forget his first meeting with 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."
