Bobby Whitlock played keyboards on the album. After the sessions, he formed Derek and the Dominos with Eric Clapton, who also played on the album. Whitlock told Songfacts
, "I was the last one to show up at the session - I was running late and my car went down on me. It was getting started, I walked in and Phil Spector said, 'Phase those drums! Phase those guitars!' He's standing there looking out like he's the captain of a ship, and he says, 'Phase everything!' A guy had to operate this phase shifter by hand, his name was Eddie Albert, and he had to work it by twisting this knob to the left, to the right, to the left, to the right. You had to do it manually then. He's saying, 'Phase this, phase that,' I come in, I'm late and Billy Preston's sitting down at the organ, Gary Brooker
is on the piano, where's my spot? Everything was on the downbeat. I said, 'I've got it, give me that little piano over there, I've got my part.' I played everything that nobody was playing - I played on the upbeat. That's me on the electric piano playing the exact opposite."
