Retro Radio has a podcast of a Command Performance broadcast with Judy Garland. Follow this link.
Judy is 19. Some years later she was a regular on Bing's own show, producing with Bing, in my opinion, some of the most memorable items from those shows, both with the hilarious sketches and the duets .
Thanks Richard for that entertaining half-hour during which reference was made to Ballarat, Australia. During World War 2 many US service personnel were posted to Australia including, if I remember correctly, the husband of Bing's sister Mary Rose.
