It's Sept. 11, 1968 in Studio Two at Abbey Road. The Beatles had just finished their ninth attempt at recording "Glass Onion" when John Lennon, the song's chief writer, calls out to Chris Thomas sitting in a control room above the studio. "What do you think upstairs, Chris?" The 21-year old assistant to producer George Martin replies on a talkback microphone, "It wasn't quite together on the first verse, I don't think." And so, The Beatles launch into take 10 (which you can hear below).
