This made for interesting morning listening - nice time-frame/gender progression.

Wondering about Billy Gibbons at beginning of Pearl Jam version, and who the others on stage were, yielded this:

"Fortunate Son" (mixed from various dates, with Johnny Marr, Betchadupa, Cheetah Chrome, Sleater-Kinney, Corin Tucker, Mike Tyler, Steve Earle, Jack Irons, Ben Harper, Billy Gibbons, Ann and Nancy Wilson of Heart, Idlewild, and the Buzzcocks)

I thought that might be Ann Wilson. Pearl Jam version best, and Ann Wilson better argument for female voice than Cat or Brandi.
