Who is the black lady singer.
Mavis Staples of The Staples Singers. That was Pops and her sisters doing back-up. 1976. The Last Waltz. Most of those folks are dead now except Robbie, Garth, and Mavis.
Robertson is a self centered prick and pretty much responsible for breaking up The Band. He's younger than the rest and since he's the only one left who's coherent, so he gets to write the narrative.
