The 1909 musical comedy "The Prince Of To-Night" featured "I Wonder Who's Kissing Her Now" (Howard - Hough - Adams). Canadian tenor Henry Burr was a member of The Peerless Quarter when this was recorded. The song was used in the 1947 motion picture of the same title concerning the life of songwriter Joseph Howard.

The Ted Weems Orchestra and Perry Como released a cover of "I Wonder Who's Kissing Her Now" in 1937. This was edited to include the vocal.

Perry Como also recorded a more mature version of "I Wonder Who's Kissing Her Now" (Howard - Hough - Adams) in 1947 for RCA Victor. This reached number two on Billboard. Following a court appearance the name of Harold Orlob was added to the composer credits after the movie became popular.
