Watched online, good print.

Comic mayhem with lots of songs and dancing. I would bet that was particularly welcome 3+ weeks after Pearl Harbor.

Nothing particularly memorable, except perhaps MA dancing "ballet" in tights. MR is man-chasing as usual.

On the list for the Tap! Appendix for Whitey's Lindy Hoppers, added from Jazz Dance: The Story Of American Vernacular Dance by Marshall & Jean Stearns, 1994. They are amazing athletes.

I've left this on my wishlist to buy a copy if officially released.
