Nobody's Sweetheart, also known as Nobody's Sweetheart Now or You're Nobody's Sweetheart Now, is a jazz and pop standard published in 1924. It was written with music by Billy Meyers and Elmer Schoebel and lyrics by Gus Kahn and Ernie Erdman. The tune was introduced on Broadway by Ted Lewis in The Passing Show of 1923 and was first recorded on February 22, 1924 by Isham Jones and His Orchestra for Brunswick Records. It quickly became a favorite, with early popular versions by Isham Jones (1924), Red Nichols (1928), Paul Whiteman (1930), Cab Calloway (1931) and the Mills Brothers (1931). Over the years it has been recorded by many artists—Louis Armstrong, Doris Day, Bing Crosby, Chet Atkins, Leon Redbone and Captain Sensible among them—and has appeared in films and on radio, making it a lasting Dixieland and swing era staple rather than tied to a single album release.
