FYI: There's a detailed article in the Billboard 1944 Music Year Book, titled "V-Disks Help Hasten V-Day", with a "List of Artists Who Have Recorded V-Disks", p. 148, 149, 204-208.
Thanks, Twitster, for the fantastic info about V Disc. One could add that Bea Wain, now nearly forgotten, had been the gorgeous "girl singer" with Larry Clinton's big band for about two years, featured on the top hits "Deep Purple", "Heart and Soul", and "My Reverie" among others, before she went solo in mid-1939. Born April 30, 1917, she seems to be alive and well, aged 97.
This represents the debut of the V Disc series which began in October, 1943 with the issue of the "A" release package, involving V Disc catalog numbers 1 through 30. Each month thereafter brought a new release package in alphabetical order until the label was discontinued in May, 1949 ("FFF" release, catalog number 905).
The recordings included a wide-ranging hodge podge of all music genre, sourced from commercial recordings, radio broadcast rehearsals and air-checks, V Disc recording sessions, Hollywood film soundtrack takes/outtakes, concerts and recitals (there were even several "blooper" issues). From jazz to polka, spoken word to classical, it's all found within the series.
Of course, these recordings were issued to military installations and units only. They were prohibited from both being commercially released or even owned by civilian collectors (currently all are within the public domain). Following the demise of the label, installations were ordered to destroy all copies of the releases and most of the master/stamper metal parts also were discarded. The Library of Congress maintains a full set of the label's output; the National Archives managed to save a limited number of the master/stamper parts for posterity.
The above release represents the U. S. Army's issue of the recording. For a limited time there were separate issues for the Navy and Marine Corps, with their own label designs and catalog numbers. Eventually, these separate labels were dropped and all subsequent releases were issued using the Army's label design.
