"Who?" (1925) is a popular song (sometimes written as "Who (stole my heart away)?") written for the Broadway musical Sunny by Jerome Kern, Otto Harbach and Oscar Hammerstein II. The song was featured in the film version of Sunny (1930) starring Marilyn Miller.
In 1925, George Olsen and his Orchestra had a million-selling, six-week run at number one with the song. Tommy Dorsey and His Orchestra with vocalist Jack Leonard had a hit with the song in the late 1930s, which was patterned after Dorsey's 1937 recording of "Marie." Judy Garland sang the song in the Metro-Goldwyn-Mayer biopic Till the Clouds Roll By (1946), loosely based on the life of Jerome Kern.
