 Originally sung in Irish Gaelic, the song was popular through the early 20th century.It enjoyed a revival when an updated swing version sung by Irish-American singer/actress Judy Garland was featured in the 1940 film Little Nellie Kelly.The updated version is true to the original musical air, and incorporated original lyrics by MGM Musical Director Roger Edens,
and featured Garland singing the song to George Murphy using some of the original Gaelic lyrics in the first chorus, which was true to the traditional air, before moving into an up-tempo swing version typical of the era.
