These are two, ultra-rare broadcasts of Martin Block's famed Make Believe Ballroom. The first segment is a touching rarity from 1960 that was actually the final broadcast of the Ballroom. Segement two, from 1940 Ballroom program, is an astounding, 15-minute jam session on the blues that features Gene Krupa (soloing, of course), Count Basie, John Kirby, Jack Jenny, Tommy Dorsey, Roy Eldridge, Harry James, Bunny Berigan and an unbelievable Coleman Hawkins. Just remarkable!
