Charlie Rose is a pretty good interviewer. Not a host, but an actual journalist that does his research and asked pointed questions. He's not writing for a music magazine, but interviewing for a national broadcast. As such he's not pulling punches and is making the story of this "unknown" legend compelling. He also wants the audience to see that Gatton is for real as a player. Danny's was completely up to the task, so it was nothing but good.
I never knew Charlie had such a strong accent. It's not there now when he does his interviews on PBS and other venues.
