Louis Armstrong & His All-Stars

Armstrong's All-Stars weren't formally established until August 13, 1947. However, the band had already performed and/or recorded several concerts/sessions by then under that name: Louis Armstrong and His All Stars, May 17, 1947, at Town Hall, New York City (recorded by promoter Ernie Anderson; of which only 6 songs were initially released, the rest eventually released in full in 1983 by RCA France); Louis Armstrong and His All Stars, June 10, 1947 (4-track single, studio recording, Victor); and possibly NBC Radio Broadcast Transcription (radio), New York, NY; June 19, 1947, Winter Garden Theatre, New York City.
