Tell those tossers that this is what Paul McCartney said it was about: The Liverpool legend explained: "I had a dream in the Sixties where my mum who died came to me in a dream and was reassuring me, saying: 'It's gonna be OK. Just let it be...'"

McCartney's mother was also named Mary, which has been cited as an inspiration for the "Mother Mary" lyric."

Definitely not Marijuana, but the reference to Mary, Mother of God was also intended.
