Yes I remember Paddy Clancy singing "Kevin Barry".
not long ago I was at a talk about local history and the speaker - wanting to impress on us the usefulness of oral history and the relevance of songs to historical research - asked how many people knew what day of the week Kevin Barry died on. Several of us were surprised that we did know, because we know the line, "It was on a Monday morning, high upon the gallows tree." But is that correct? Someone who is good with calendars might like to check it out for us. If the song was "Terrence Ward of The Irish Press" and we are singing that verse as written, I expect we do have it right.
