Richard Rodgers and Lorenz Hart wrote "The Most Beautiful Girl in the World" for their 1936 stage extravaganza "Jumbo." She must be quite a swinger judging from this hipper than hip arrangement with Tommy Dorsey playing on his muted trombone and accompanied by strings and a back-up vocal group adding to the musical pallette. It's very infectious with an interesting scatting break for the vocalists and strings.
