I couldn't get my math to work out. 11 + 2 = 13, but I saw that I had 14 on my list, looked (and overlooked) for the problem until I saw that I had listed The Wexford Massacre twice.
In the United States, the 11 are found on Irish Folk Favourites Vol. 3 [St. Clair] available from Amazon for $6.98, well worth it. You might want to check with Dick first.

As Snuffy says, the other two are from some other source and are more frequently anthologized than the 11 from his LP.

I agree with Lighter completely. You get the feeling that they meant every single word they sang with absolute conviction. That counts for a lot.
Snuffy (and others who might know): Given the interest in their old recordings, is there any chance at all that they might record again? They really are not old at all. Just a bit of wishful thinking there, I guess.
