The Beatles in the Film ‘Help!’, 1965

“We would occasionally get stoned on the way to the film set. My main memory is of being in hysterics because for all of us, one of the great things about early pot was the sheer hysteria— the laughs. Things could appear very very funny, hilariously so. And nobody quite knew why we were laughing, and of course this made it even funnier. It was like little kids giggling at the dinner table. I remember one of the scenes, it was after lunch and we’d crept off into the bushes and come back a little bit sort of ‘Hi there!’ pretending we’d had a glass of wine too many or something.” – Paul McCartney
