"Macushla" is the title of an Irish song that was copyrighted in 1910, with music by Dermot Macmurrough ( Harold R. White) and lyrics by Josephine V. Rowe.
The title is a transliteration of the Irish mo chuisle, meaning "my pulse" as used in the phrase a chuisle mo chroí, which means "pulse of my heart", and thus mo chuisle has come to mean "darling" or "sweetheart". [1] [2]
"Macushla" became the signature tune in the 1912 musical Macushla by Chauncey Olcott. [3]
The song was recorded by a number of operatic tenors including John McCormack, [4] James McCracken, [5] Christian Ketter, [6] Kenneth McKellar and Josef Locke. [7]
