I've seen clips of obvious audience filmed videos from shows dating back to 1977 ("The King & I" w/Yul Brynnur & Constance Towers) and some from the 1980's which are surprisingly good. A few of these (such as "Rags" & "Legs Diamond"
will most likely never be revived again outside concert productions, so I did manage to watch the whole video without squirming. But as an avid theatergoer since childhood, I prefer to be there to see it live and capture every magical moment. I saw Annie & Mickey in the original "Sugar Babies" (on tour), and the audience filmed footage of the show is wretched, but in my mind's eye, I can recall every moment I saw live at the Pantages Theater.
For shows that are difficult to get tickets to, I don't even want to see clips before I actually see it live. Certainly the artists deserve to have their works protected, and I wouldn't want to be next to somebody obviously filming, although I'd be hesitant to make a disturbance. It's a tough call to make, and even artists disagree on what's right/wrong or ethical, etc. For the professionally filmed shows, they are entertaining, but as somebody who loves live performance, I just feel like the emotional element is missing when it's on a TV screen or computer rather than in the audience. Some people become shut-in's and anti-social because of Times Square crowds and audience behavior, and often, I'm upset by how people act, but you can't let one bad experience take away your passions. I'll watch it live, often 2 or 3 times, and if somehow, I get a copy of numbers or in a few cases, the whole show, I'll give it a perusal, but usually, they are nearly impossible to watch because of bad sound or photography, or angles that make the viewing experience claustrophobic.
