This idea came to me years ago, to be able to give the students a chance to play with a band. If they don't otherwise have the luxury of having a band right there, then this would serve as something that they would have. It's got the charts written in there. Like for instance, Hallelujah was a thing that Buddy Rich played. So I talked about the arrangement. On the CD, my playing is muffled almost completely. It gives the drummer a chance to play along with the band. The chart is in there. I've got Buddy Rich, Hallelujah. Liza, by Chick Webb. Remember that one?
