Glenn was the leader of the band in getting stuff done. He was the doer. He understood when we agreed to do [the film] it had to be honest. He's like, "I don't want a fluff piece." His willingness to be completely honest, warts and all, made a huge difference in the film and set a precedent for the others in the interviewing. Joe Walsh, after seeing a first cut of the film, asked to be re-interviewed, because he realized how open Glenn was being. When we interviewed engineer Bill Szymczyk, he said, "You're not going to believe what I have for you." He played [the tape of the onstage argument between Frey and Felder on their
Long Run tour] and we were like, "Holy shit, this is great." We told Glenn we had it, and he said, "Go for it, man."
