"Goodbye, My Coney Island Baby" is a popular barbershop song composed in 1924 by Les Applegate.
[1][2] The tune was later adopted by Texas A&M for their Aggie War Hymn, the words of which were written in 1918 by J.V.
[3] "Coney Island Baby" is often included in the repertoire of a barbershop quartet.
The original lyrics are not related to Coney Island directly, but are about a man abandoning his lover (whom he apparently met at Coney Island) to avoid marriage, the drudgery of which is lamented in the middle section, often known separately as "We All Fall."
It also appears in season 6 episode 2 of Frasier (titled "Frasier's Curse") when the title character begrudgingly reconnects with his high school Barbershop quartet at the end of a miserable reunion party.
