I have a version of this in Paddy Tunney's book - The Stone Fiddle (I haven't checked the records to see if it's on one of his that I've got). It appears in the chapter called William Monaghan of Tullyhasson: "When the applause had died away, William flung his hat on the floor and declared he'd sing The Song Of Temptation:". The words following the above in this version are:

I fear your wear some damp must bear
Or surely you'd reveal them

If you want I'll post the whole version - let me know.
