Macushla

"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".

"Macushla" became the signature tune in the 1912 musical Macushla by Chauncey Olcott.
