This clip comes from "The Powers Girl" (1942). The arrangement appears to be the Jimmy Mundy revision Benny commissioned in 1941 of the Mary Lou Williams classic, originally immortalized by BG's '37 band. Decimated by the WWII draft, this transitional ensemble was trashed by critics as one of Goodman's weakest...but six decades later, Benny and the band sound awfully good indeed! Bonus: Watch for George Murphy and Dennis Day. ("The Powers Girl" also gave moviegoers a relatively rare opportunity to see Benny sans specs.)
