Norman Granz's Jazz at the Philharmonic (JATP) concert series began in Los Angeles at the Philharmonic Auditorium in July 1944. For the balance of the year, the concerts—featuring black and white star musicians—attracted integrated audiences whose members were often whipped into a stomping frenzy by the extended solos.
Granz showcased a growing number of black jazz artists in 1944, and his program notes advocated on their behalf. All of which soured the L.A. venue on the series and Granz's use of the word "Philharmonic" in his promotions. So in 1945 Granz took his cavalcade of jazz all-stars on the road, touring from city to city and using the word philharmonic as a generic term—to retain the brand and promote jazz as being on par with classical music.
JazzWax reader Betty attended the spring 1947 performance (the JATP's fourth national tour) and wanted to share her concert program with JazzWax readers. So her friend Chris sent along the entire program, page by page. Here it is (click an image to enlarge):
