The Beatles have certainly enjoyed a successful week, with every last scrap of digital detail in their reissued albums being pored over by expectant fans. Paul McCartney has been doing some publicity to promote the reissues—not that he needs to, the sales will be astronomical—and has spoken to Entertainment Tonight about the band’s drug use.

"We were overdoing substances and really getting crazy, as we all were,” he said. “We'd be falling asleep, the kinda thing when you can hardly get your head off the pillow. You go, 'Woah, I'd better get my head off this pillow.'” Yes, The Beatles were getting some good shit back in the day.

McCartney also revealed the inspiration for the song “Let it Be,” which came to him in a dream. "I had a dream, where my mother, who had been dead, by then, 10 years came to me in the dream and was very sort of helpful and very calming, and it was lovely just to see her... and she said, 'Don't worry about it... Let it be.'”
