According to Doughboys in Ireland, there were those who sang their way through WW2. Radio tenor Kenny Baker plays Manhattan orchestra leading Danny O'Keefe, who is drafted into the army along with a Ritz Brothers-like quartet called The Jesters. Stationed in Ireland, Danny believes that his New York sweetheart Gloria (Lynn Merrick) has forgotten about him, thus he inaugurates a romance with Irish colleen Molly Callahan (Jeff Donnell).
