Questions about U.S.O. events/WWII footage in general

I have a couple of questions about U.S.O. events during WWII

1) Would U.S.O. events have been filmed in any official way, especially if celebrities were present?

2) How would celebrities end up posing with soldiers during such events?

3) If there indeed films of U.S.O. events, how would one find them?

I ask because I believe the following photos from my grandpa's WWII collection are photos from a U.S.O. event sometime around November 1942. I am not sure where it would've exactly happened, but I believe my Grandpa was stationed at the Presidio of San Francisco at the time. I am curious for one how he and the other soldier would have a model like Jinx Falkenburg sitting for a photograph with them, I am also curious if this show might have been filmed as one soldier has an old video camera in his hand; I wonder if, since a celebrity was attending, if there were any official films made of the event--if this is the case I might get to see my grandpa, and perhaps even hear what his voice sounded like. I'm also curious if there is any possibility that I could find footage of him later on, when he was in the Rhineland & Northern France campaigns for example.

These are the photos

 

I know very little about this subject, but as usual I'm not going to let that stop me from commenting.

For many performer's (actor's, dancer's, singer's and comedian's) "doing their bit" was in appearing at various USO fuctions here at home and later overseas. A few were filmed for newsreel's to be shown to wider audience's, but the vast majority were not.

It was, however, a cultural custom in the '30's though the '50's for a Nightclub or fancy resturant to have a photographer on site to take pictures for those who wanted a momento. Celebrities of the war period posed with ordinary service personel in this manner to both do their bit and to help raise moral.

 

I was born in January of 1940 so have few memories of the war but in the period afterward saw films of Bob Hope and his entourage touring the war theatre. They showed up on Newsreels and early B&W TV for a number of years after the war. Try Googling Bob Hope and other performers as we as YouTube. Glenn Miller died somewhere over the North Sea, you might find something on him and his band.

I've tried all the things you guys have suggested...I'm coming up empty.
I think if I could find some itinerary from 1942 of USO shows (I would think this is indeed a USO show, right?), I could narrow down the exact event, as in the exact date and place, that these photos are from, and work from there. My only real goal or hope in this is to find some footage of my grandpa, which ideally would have sound.

 

Al Jolson ?

Al Jolson - Wikipedia, the free encyclopedia

"He did as many as four shows a day in the jungle outposts of Central America and covered the string of U.S. Naval bases. He paid for part of the transportation out of his own pocket...."
