This is from Sun Valley Serenade (1941) [IMDb]. Later featured from the same film: I Know Why (And So Do You) – Glenn Miller (1941). The man at the piano is John Payne, famous for defending Santa Clause as Fred Gailey in Miracle on 34th Street. The admiring girlfriend is Olympic Skating Champion Sonja Henie.
When Phil Corey’s band arrives at the Idaho ski resort its pianist Ted Scott [Payne] is smitten with a Norwegian refugee he has sponsored, Karen Benson [Henie]. When soloist Vivian Dawn quits, Karen stages an ice show as a substitute.
Ice show! Sonja Henie! Box Office Boffo! Just like all the movies featuring Esther Williams ended up with her swimming.
But never mind all that. Here’s the razzmatazz.
