From the Washington Post
The Dec. 11 obituary of Richard Pryor incorrectly said that he was nominated for an Academy Award in 1972 for best supporting actor in "Lady Sings the Blues." It also incorrectly said that the cover of his 1975 album "Is It Something I Said?" depicts Klansmen; the album cover shows dark-robed figures. Link
Chicago Tribune:
In the obituary of comedian Richard Pryor in Sunday's paper, Pryor was described as having made "his starring debut as Diana Ross' piano man in 1972's `Lady Sings the Blues.'" In fact Pryor played the role of singer Billie Holliday's piano man, and Holliday was played by Ross. Link
