Rhythm on the River stars Bing Crosby and Mary Martin as star-crossed songwriters who step out from the shadows in the hopes of making it big. Oliver Courtney (Basil Rathbone) is a well-known composer of hit songs who is very much in demand. However, beneath the gloss of a well-polished performance lies the truth about Oliver's talent—it's the work of ghostwriters! Bob Summers (Crosby) writes the tunes and Cherry Lane (Martin) writes the lyrics—only neither knows the other exists and both believe they are collaborating with Oliver. When the two happen to meet, they discover they have a lot more in common than they ever imagined! © 1940 Universal Studios. All Rights Reserved.
