Here are the notes that Vincent H. posted in the chat during the June 13 Singaround:

The title of the song translated into English is “Jesus Jesus” the chorus loosely translated reads “Jesus ,Jesus, Keep the sheep in the fair glens and on the pleasant mountain grass” This chorus is a traditional prayer that the people of Rinn in Co. Waterford had about 1947 (may be for many years before that)The stanzas and the melody were composed by Máire Ní Dhuibhir (Mary Dwyer) about the late 1970’s
