“Jazz in Film” continues its Monday and Thursday run this month with tonight’s prime-time lineup, which includes this 1972 Diana Ross showcase. She plays jazz singer Billie Holiday, and does a fine job with both the vocals and the tragic drama. Co-stars, by the way, run the gamut, from Star Wars stalwart Billy Dee Williams to The Jeffersons sitcom star Isabel Sanford – with Richard Pryor (pictured, with Ross) as the piano player.
