Just caught a great PBS pledge week special that featured a Stax/Volt revue filmed in Oslo Norway in '67. No Carla, but Otis ruled the stage.
I was gonna say "an all-black show for an all-white audience", but i guess Steve Cropper was on stage somewhere...
Watched
Wattstax the other night, if you haven't seen it, do! the music is pretty good, of course -- although i wanted to hear more of everyone -- but the interviews, the footage from 1972 is fantabulous!
eta: The Wattstax concert, staged in LA Coliseum in 1972 to commemorate the 1965 LA riots, was an all-back show for a mostly all-black audience featuring Stax artists. Issac Hayes headlines, but Rufus Thomas brings down the house w his two tunes.
