I heard this song performed by Luke Kelly back in the 1970's
It begins as follows;

How sad my misfortune how vain my repining
the strong rope of fate for my young kneck is twining
my strength is departed my cheeks sunk and sallow
while I lie here in chains in the gaol of Cluain Meala.

Cluain Meala is Irish meaning 'Vale of Honey'
The English form is Clonmel, as in the Co. Tippery Town.
If any one has the lyrics or better yet the recording please contact me. seamuslucey@eircom.net
