On April 5, 2010 (from 9 to 10 pm, US time), Tv One will air an episode of their Unsung series, entitled "Unsung Uncut". It will feature full length performances by many artists featured in this series including Shalamar, Bootsy Collins and the one and only Donny Hathaway. Donny will be performing "The Ghetto" from his May 14, 1970 appearance on the Soul show.
PS : If someone could record it, I would appreciate a copy. Thanks.
EDIT : UNFORTUNATELY, THE GHETTO WAS NOT BROADCASTED. "PUT THE HAND IN THE HAND" FROM THE FLIP WILSON SHOW (1972) WAS AIRED INSTEAD.
