"I've Heard That Song Before" is a 1942 popular song about nostalgia  with music by Jule Styne and lyrics by Sammy Cahn. It was introduced by Martha O'Driscoll (dubbed by Margaret Whiting) in the 1942 film Youth on Parade. The song was nominated for the Academy Award for Best Original Song in 1942 but lost out to "White Christmas".
It was recorded by Harry James and his Orchestra with Helen Forrest on vocal on July 31, 1942. This was the last day of recording before the Musician Union's ban. The recording was issued on Columbia 36668 and became a number one hit on both the pop charts and the Harlem Hit Parade in the US in early 1943. This version of the song can be heard in Woody Allen's 1986 movie Hannah and Her Sisters.
