Cynthia's In Love is a 1942 song - written by Jack Owens, Billy White and Earl Gish - with arrangements by Lou Halmy. It was published as sheet music for orchestra and piano in the Musicals genre. The original hit recording was by Bob Eberly and The Song Spinners, released in 1946 on Decca 18896 as a 78 rpm single. The lyrics describe Cynthia as a bright, starry-eyed lover whose charm lights up every rendezvous - and the tune later found a home in jazz through Cannonball Adderley's 1955 recording, making it a notable cross-genre piece.
