There's that video of Ball and Chain from Monterey Pop festival; their coming out performance more of less. Occasionally I watch "First Time Viewing.." videos and there is one that is pretty funny. Several Gen Z girls, slackily listening and talking over the music for about 15 seconds and then just listening. They stopped the video and one commented "that girl listening looks like she feels like I do". She couldn't have known the amazed audience member was Queen of Laurel Canyon: Mama Cass Elliot. Cass' expression showed what kind of mind explosion occurred when Janis sang. Wished for many it went on longer.
