I've only seen her once in concert, at San Francisco City Hall on Christmas Eve 1978, shortly after Jonestown and the Moscone/Milk assassinations. It wasn't a concert exactly, more like a night street rally. We took our daughters, then 4 and 2, and they couldn't possibly have appreciated it (I don't think), but we stood in the street in the dark and sang, and it was very good. Don't know how I'd review it as a performance, but nobody cared then and I doubt that anyone who was there then cares now.
