Hi, anybody knows more about that show? I'd been on the road quite often in the last 30 years and i never saw an artist or a band do a benefit for his crew.

I was still in high school. My 2nd show, but my first time to see the Dead in the wilds of Winterland. If I remember correctly, we arrived to see, "Grateful Dead, NRPS, Toilet Bowl" listed on the marquee. Turns out that after the show, Bill Graham had a touch football game (get it?) vs. the Dead's crew - but I missed all of that part.
As for the show, Grace Slick came onstage with the boys at the beginning of the second set. She seemed completely ripped. They played a short bluesy jam with Grace lending some off the cuff vocals for a minute or two before she began going from one mike stand to another, raising, lowering and generally screwing them up. Bill Graham came on and escorted her off to the side of the stage, where they could be seen dancing later during Truckin. Also, during the end of Sugar Mag, Graham slowly brought the house lights up until the room was as bright as day. The tape doesn't show anything too far out of the ordinary, but it was one of the greatest Sugar Mags I've ever seen - Sunshine Daydream!
