In an interview, when Paul McCartney talked about his memory with Michael Jackson:
It was actually upstairs, here. In this office. Michael originally rang me, and said ‘do you want to make some hits?’ I didn’t know who it was, I didn’t recognise his voice at first, but I dug into it, and then I said ‘yeah, sure.’ He came along, we agreed to meet in here, at the piano upstairs. We just sat around with a guitar, at the piano, and we just sort of went ‘what shall we do?’. We just started, and it came very easily. I was quite excited to write with him, he was excited to write with me, so we were just popping off each other. We just did it, it was a very short session, and we were in the same room.
