I'm listening to Episode 44 of Something About the Beatles and its the Yoko episode. While describing her life before John they just dropped that in 1966 Yoko and her second husband Tony Cox actually drew up a legal document (not sure if official or not but they still drew it up) promising each other a 50/50 split of whatever money Yoko could get out of John Lennon.
Holy FUCKING shit. I need to find a source on that but jesus WEPT
