There was a great piece on Tubas/Euphoniums and Tuba Christmas. Michael Salzman (not sure on the spelling) played a piece on a Hirsbrunner CC tuba beautifully. They also interviewed the Tuba Instructor at Wichita State University and showed some of the Tuba Christmas events in the area. I found it by accident. They paid tribute to Harvey Phillips as well and talked about the origin of Tuba Christmas.
