Mystery Entertainment Autographs c. 1949 - Help needed on a couple dozen

[ATP]

Hi Everyone,
I've got a small stack of signed album pages here that came out of three albums circa 1949. Almost all of them were music or entertainment related, and they appear to have been acquired likely in the New York area. There were some bigger names like Louis Armstrong, Bob Hope, Spike Jones, and many of their band members, but also some obscure performers that appeared on shows, Dancers, Jugglers, Comedians, etc. There are also some opera, ballet, classical and composers. These are the ones I am struggling with identifying, if anyone is up for a mid week mystery I will take any help I can get. Thanks for looking.

Here are the ones that the sharp eyes here have been able to identify and I have since removed, to make it easier to focus on the unidentified ones. I am going to leave the names up in case one sparks an idea on another
