Many stars from Hollywood give tribute to the USO units who since 1942 have entertained troops overseas. They include Dick Powell, Marilyn Monroe, Jack Benny, Debbie Reynolds, Danny Kaye, Merle Oberon, Frances Langford, Joe E. Brown, Harry Truman, Dwight D. Eisenhower and Bing Crosby. Included with these celebrity anecdotes, celebrating this 20th USO anniversary, is a clip of Irving Berlin singing his own song: "Until the Fifth Army Comes Home."
