I didn't know that. Someone did a 12-minute video on that concert for YouTube, but the audio has been deleted. But there is this: https://www.youtube.com/watch?time_continue=238&v=1z3XBNKRajg
Saw the James Gang live they opened for Joe Cocker at the Warehouse in NOLA. James Gang stole the show.
The end of that song has always driven me nuts. It just keeps going and going and well, it's about 3:30 too long. Can't stand when they let it go on the radio.
