It was suggested that I also have a post on Ginger Rogers since I had one on Gene Kelly and another on Fred Astaire earlier in the month. So, without further ado...
The clip is a deleted segment from the 1942 film Roxie Hart, which we do not own in DVD, but we do own these:
Follow the Fleet. [DVD FOL]
Shall We Dance. [DVD SHA]
Stage Door. [DVD STA]
Swing Time. [DVD SWI]
