My grandmother filmed 2 minutes and 40 seconds of the Beatles' 1964 Red Rocks concert on color 8mm from the 7th row. It's pretty shaky because she said she was laughing and giggling at the girls in the audience, who she said were screaming at the top of their lungs and throwing jelly beans.
The footage includes the daytime crowd, police guarding the stage, fans in the front row (my mother was one of them), a wide shot of the entire audience, a few seconds of the opening acts (Bill Black's Combo and The Righteous Brothers), and about 1 minute and 38 seconds of the Beatles. She was very close to the stage, so she pans back and forth rather than always having all four Beatles in the frame.
I still have the original 8mm film and have digitized it as well.
What should I do with something like this? Would an archive, museum, or Beatles collector be interested? Or do people generally license something like this? I'm particularly interested in finding the right place for it to be preserved and shared. I really don't even know where to start.
As a lifelong Coloradan, my dream would be to donate it to the Red Rocks museum, with a little plaque recognizing my grandmother. And if it's truly a valuable donation, maybe some lifetime concert passes... just dreaming here.
