That's so great!
But also great is what YT followed it with for me- the Dick Cavett show that aired the day after Woodstock, with Jefferson Airplane, Joni Mitchell, and Crosby&Stills. I found it interesting that JA played it straight even though the guitars clearly were not plugged in. So often they mocked the faux live performance by doing things that would clearly screw up the guitar playability (a rubber octopus through the strings, etc.) It could have been because they were exhausted and fried, having just come from Woodstock, but I like to think they respected Dick for the stage he gave rock musicians in a time so many looked down on them. This appears to be a recording from a TV, which begs the question of how the "We Can be Together" lyrics got past the censors. JA had a contract that let them do whatever they wanted lyrically and musically from RCA's standpoint (or so I have read), but network censors wouldn't care. Anyway, this is a great show.
If I could go back and see any one concert I missed, it would be Woodstock. Mud, rain, roaches and all. 8^)
