It’s not easy being a band leader. The Rev. Often describes it as “babysitting grown men.” In this bit of the recordings made in secret by his pianist, Buddy goes off on various members of the band. His legendary outbursts have long been enjoyed in bootleg form and, it seems, especially by comedians. (Larry David and Jerry Seinfeld used a few lines from the recordings pretty much verbatim on several Seinfeld episodes.)
