I LOVED that movie, kat!The only ones I remember from WW II are:
"Five Minutes More", recorded by Glenn Miller orchestra with Tex Beneke on vocal "Roll Me Over," but I can't rememeber who recorded it "There's a Tree in the Meadow" made popular by Margaret Whiting I wonder if "May I call you sweethert" is actually, "Let Me Call You Sweetheart," which predates WWII "Bless Em All," which I associate with being a British WWII song, but I have no proof of that.
