Bob Dylan drove down from Woodstock on the afternoon of the 28th to meet them in their Park Avenue Hotel in New York. He introduced them to marijuana, an event that served as symbolic a turning point in the music of the Beatles.
Brian Epstein kept saying "I'm so high I'm on the ceiling, I'm up on the ceiling."
Paul McCartney response, however, wasd much more telling "I'm thinking for the first time, really thinking."
The Beatles would go on to make the gradual transition from wide eyed teenagers to the most visible of the psychedelic pioneers. The Beatles released Help ! shortly after but their first mature masterpiece was Rubber Soul, with songs like "Nowegian Wood (This Bird Has Flown)", "You Won't See Me" and "Nowhere Man".
