"Buffalo Gals" is a traditional American song, written and published as "Lubly Fan" in 1844 by the blackface minstrel John Hodges, who performed as "Cool White." The song was widely popular throughout the United States. Because of its popularity, minstrels altered the lyrics to suit the local audience, so it might be performed as "New York Gals" in New York City or "Boston Gals" in Boston. The best-known version is named after Buffalo, New York.
The chorus is:
Buffalo gals, won't you come out tonight?
Come out tonight, Come out tonight?
Buffalo gals, won't you come out tonight,
And dance by the light of the moon.
