The Beatles may have stayed (and dropped acid) at 10050 Cielo Drive in the mid-sixties, something (apparently unwittingly) implied by John Lennon during a 1974 Rolling Stone interview.
And then, well, we just decided to take LSD again in California…We were on tour, in one of those houses, like Doris Day’s house or wherever it was we used to stay. And the three of us took it. Ringo, George and I… And a couple of the Byrds… Crosby and the other guy, who used to be the leader…McGuinn. I think they came round, I’m not sure, on a few trips.
Terry Melcher, , was Doris Day’s son, the Byrds’ producer, Manson’s almost-producer, and Sharon Tate and Roman Polanski’s predecessor at 10050 Cielo Drive. Derek Taylor, the Beatles press officer, mentions going to a party at Cielo given by Terry Melcher. He says that he and his wife didn’t understand the remote control system at the gate and had never spoken to anyone from a gate before.
