Stevie Nicks -- if Christine was the Earth, I guess Stevie was the sky. Out there somewhere. Stevie's chiffon twirling image was a very strong thing for the group. The sense of the ethereal that she brought to her songs. And her voice. She brought quite a bit into the situation, obviously. She and I together brought a lot. Probably my main contribution was to take raw material and fashion it into a sound in the studio. There were other things too, certainly. But overall, I don't feel that I was tapping into my potential fully then.
