Who the hell is singing on this? It doesn't even sound like Mick. Anybody know what I am talking about?

jagger had starting have throat issues slightly before the b-stage...by the time they got to the warhorse parade, he had barely anything left in his voice. but for those of us there, it was fun to see mick make up for his voice problems with some amazing showmanship. the band, of course, postponed their next gigs in san jose due to this issue....

Yeah, if you listed to 'Brown Sugar' on that, his voice is totally unrecognizable at that point. But as StonesTod said, I recall reading reviews where he put extra effort in his physical perfomance to compensate.
