"I'll Be Seeing You" is a popular song published in 1938 by Marlo Music Corporation, with music by Sammy Fain and lyrics by Irving Kahal. Its subject is missing a loved one. The song was inserted into the Broadway musical Right This Way, and it became a wartime hit and a jazz standard.
The 1944 film I'll Be Seeing You took its title from the song. Notable versions include those by Dick Todd (1940), Bing Crosby (1944), Billie Holiday (1944) and Frank Sinatra. Dick Todd's recording dates from 1940, before the song's wartime success, while the Crosby and Holiday versions appeared in the same year as the film.
