I just get silly inside my head and I start to think about something and in my head I start twisting it around, contorting it and envisioning it in different ways.
I still like to keep tapes of the few minutes before the final take, things that happen before the session. Maybe it's superstitious, but I believe if I had done things differently - if I had walked around the studio or gone out - it wouldn't have turned out that way.
