They sounded great today, and did perform many of the old classic tunes as well as several "new" ones (as they said, that could mean they're as old as thirty-five years). The singer was Darby Gould, formerly with Jefferson Starship. She was good—no Janis (there will never be another Janis), but very good. Big sassy voice.
In commemoration of the original band, here's a 1968 TV show performance of "Summertime" and "I Need a Man to Love," both of which they played today. The picture quality is mediocre, but the sound is decent.
