Never mind the fact he's playing a sousaphone, not a tuba. I'm sure the guy knows. Why he ever felt he'd receive a bit of notoriety from this nonsense is beyond me. I can only assume he was kidding.
I felt the need to share that I learned today my wife never heard of the movie Deliverance and she's never heard any renditions of Dueling Banjos. I understand her being from the West Indies may cause her to be out of the loop of many things we've grown up to automatically recognize. What I find the most bewildering, when I played it for her she started dancing a jig as well as any moonshine-hustling hillbilly in the Appalachians. Confusing, very confusing indeed.
