Broadcast of Prom 57: Swing No End Singer and broadcaster Clare Teal heads the charge in this big band spectacular. Travel back in time with this rip-roaring Prom to the 1930s and 1940s and celebrate the irrepressible music of Duke Ellington, Benny Goodman, Count Basie, Tommy Dorsey, Stan Kenton and more, plus a special tribute to the unassuming giant of the big band world, Mary Lou Williams. Band leaders Guy Barker and Winston Rollins take to the stage alongside their eponymous big bands with help from a myriad of guest artists.
