Ringo: Grass was really influential in a lot of our changes, especially with the writers. And because they were writing different material, we were playing differently. We were expanding in all ares of our lives, opening up to a lot of different attitudes.
Paul: One thing that he did introduce us to was pot… Bob came round to our hotel, and he said to us, “Here, try a bit of this.” It is very indiscreet to say this, because I don’t know whether Bob is telling people he turned The Beatles on to marijuana. But it was funny. (the Bob Paul is referring to is Bob Dylan.)
John: Rubber Soul was the pot album, and Revolver the acid.
John: Bob Dylan had heard one of our records where we said, “I can’t hide,” and he had understood, “I get high.” He came running and said to us, “Right, guys, I’ve got some really good grass.” How could you not dig a bloke like that? He thought we were used to drugs. We smoked and laughed all night. He kept answering our phone, saying, “This is Beatlemania here.” It was ridiculous. (the song he’s referring to is “I Want to Hold Your Hand.”)
John: We were smoking marijuana for breakfast during that period. Nobody could communicate with us; it was all glazed eyes and giggling all the time. In our own world.
