"John phoned me up one morning in January and said, "I've written this tune and I'm going to record it tonight and have it pressed up and out tomorrow — that's the whole point: Instant Karma", you know." So I was in. I said, "OK, I'll see you in town." I was in town with Phil Spector and I said to Phil, "Why don't you come to the session?" There were just four people: John played piano, I played acoustic guitar, there was Klaus Voormann on bass, and Alan White on drums. We recorded the song and brought it out that week, mixed — instantly — by Phil Spector."
