Let Yourself Go....

A swell, catchy number to be sure... however there are two things that have always bugged me in this scene. First, we have a little 8 piece band that sounds like a massive studio orchestra with strings.... but then again, that happens a lot in Astaire-Rogers Land.
What really bothers me here is the line "loosen up and start to limber, can't you hear that hot marimba (marimber?)....". Not here or anywhere else have I found a version of Let Yourself Go that had a marimba or any other kind of idiophone in it. I wonder if Lionel Hampton ever played it...

 And another one- as much as I love 1930's fashion (and that's a lot), those... eyebrows. Good grief, the eyebrows. Ginger looks as cute as ever but they just don't work on Betty here (Grable, that is). A pretty silly thing to notice on such a fine movie, but that's just my wandering eye.
