I've posted my favorite Danny Gatton story here before, but for your benefit:
Many years ago, Danny was playing at Fat Tuesday, an old NYC night club. I went with a friend. It's a small place and not many people showed up, so Danny chatted with folks in the audience throughout the show. At one point, as he was strapping on his double neck, he started to tune the guitar while staring at the ceiling. My friend asked him what he was looking at.
Danny replied that he was tuning the instrument against the 60hz hum from the light transformers in the ceiling. Just a different kind of guy.
