“I’ll Be Seeing You” is a popular song about missing a loved one, with music by Sammy Fain and lyrics by Irving Kahal. Published in 1938, it was inserted into the Broadway musical Right This Way, which closed after fifteen performances The title of the 1944 film I’ll Be Seeing You was taken from this song at the suggestion of the film’s producer, Dore Schary. The song is included in the film’s soundtrack. A resemblance between the main tune’s first four lines and a passage within the theme of the last movement of Gustav Mahler’s Third Symphony (1896) was pointed out by Deryck Cooke in 1970.
