Because the American Federation of Musicians (AFM) called a strike against the major record companies in August 1942, and it lasted until November 1944, most of the songs written during the war to promote women's participation in defense work weren't officially recorded. So Connie Field had to use either modern recordings of the songs or versions from film soundtracks, like Benny Goodman's "Minnie's in the Money" from the 1943 film "The Gang's All Here."
