I love live concert movies, past and present. Some were documentaries. I thought Save Children circa about 1972, featuring Jessie Jackson and Operation Push, and many famous groups and singers. I wish I could find a copy. He presented a woman and 13 kids he said he found hiding in the bushes or somewhere. Some people like Woodstock, it scared me a little. Those hippies went and were tripping around in the corn fields, their kids have to be 45 years old. Live Aid is a favorite of some, I liked it it was a worthy cause and they had a lot of top acts. Maybe you like a newer concert, what year?
