Here’s a publicity photo from the April 15 1947 edition of the Toronto Daily Star:
Audrey Young (1922-2012) sang with Tommy Dorsey’s orchestra and then appeared in a number of films in the 1940s, mostly in small parts. She married director/screenwriter/producer Billy Wilder in 1949; they remained married until he passed away in 2002.
The Ritz Brothers were a trio of precision dancers, singers, and comedians who started in vaudeville in the 1920s and starred in a number of films in the 1930s. Jimmy Ritz (1904-1985) was the middle brother of the trio.
