Thanks for your comments everyone, but I'm going to let Chuck take all the credit. He is an incredibly nice guy and such a pleasure to work with. We worked on that piece in less than 8 hours, and he did it just prior to the Pittsburgh show. Chuck takes time out for people and makes you feel like a million dollars. His publicist once told me, "Chuck is a big deal but never acts like it." I couldn't agree more. I've met a lot of musicians, and Chuck is by far the nicest.
Really, most of the people in The Rolling Stones are incredibly friendly and I have never had a bad interview. I have so much respect for them as people, and as musicians.
I have had a few interactions with Chuck and he is a genuinely really nice guy! Every Stones fan should watch the movie Tree Man about Chuck. It is really enjoyable and shows what a great human being he is.
