from youtube. My kids' high school puts all concert performances on a youtube channel. I used to video a couple of songs per performance anyway. Last night, I thought, why bother? It's on youtube and their recording is better quality than mine (it's on a tripod with the stage centered etc.). Then, on the way home I realize I missed the obvious problem that the youtube stuff may not be there five or ten years from now when and if we want to go back and see something.
