Tonight on The Big Bands it's "That Old Arlen Magic," an homage to American songwriter Harold Arlen. We'll hear performances from Cab Calloway, Louis Armstrong, the Sauter-Finnegan Orchestra, Billy Eckstine and Ella Fitzgerald (each backed by a Billy May-led big band), Gerald Wilson, and more. The program airs at 9 p.m. (7 p.m. California time, 10 p.m. NYC time) on WFIU. And... since our regular jazz DJ is on vacation this week, I'll be filling in for him on the two-hour program Afterglow that follows immediately after... Afterglow is devoted to late-night jazz ballads and American popular song, so I programmed Ahmad Jamal's "It Ain't Necessarily So," Mel Torme's "A Stranger in Town," Rickie Lee Jones' "Ballad of the Sad Young Men," Miles' "Summer Night," Dinah Washington's "Romance in the Dark," Dexter's "More Than You Know" off the Mosaic Select... it's that kind of show.
