According to the Internet source given below, Lew Pollack was an American all-round talent and variously a singer, pianist, composer of popular music for stage and film. His musical career began aged just 14-years old as a boy soprano in the Walter Damrosch choral group. He went on to play piano in picture houses and tour the vaudeville circuit as a singer-pianist. He wrote materials both for himself and others. As a song composer, his collaborators included Erno Rapee, Sidney Clare, Jack Yellen and Ray Gilbert. The greater part of his output went however into film scores such as Captain January (1936), One In A Million (1937), In Old Chicago (1938), My Son, My Son (1940) and Lady, Let's Dance (1944). Perhaps his best known song is the evergreen Charmaine (1927). Of ragtime interest are his That's-A-Plenty (1914) and High Stepper Rag (1917).
