1) From the soundie: JUKE BOX SATURDAY NIGHT 1944
2) From a BRITISH MOVIETONE NEWSREEL 1939
3) From the movie: SWING FEVER 1943
The first clip features the Glenn Miller Modernaires with Harriet Clark instead of the usual Paula Kelly. I think the dance couple in the back looks a little like Wally & “Mousie” Albright but I’m not at all sure. The second clip is unfortunately mostly silent and it’s from a newsreel of President Roosevelt’s birthday ball in 1939. The third clip shows Kay Kyser’s band playing in front of a large group of dancers including Genevieve Grazis & Johnny Duncan who can be seen in the lower right hand corner toward the end.
