Hi Domo,

I think I found it!

Dominic Behan - Finnegan's Wake and Other Irish Folksongs
Folk-Lyric Records - PL-113

I could not find the year or track listing - but it does appear to be an American release (as you suspected). It could be a compilation of the "Collectors" EPs or a re-tilted release of Down by the Liffeyside: Irish Street Ballads, 1958—Topic 12T 35 LP.

I say that because Finnegan's Wake is on those releases...mind you it could different altogether.
I have found a picture of the cover of this album, as well as the cover of Mrs. Hooligan's Xmas Cake
1958—Collector JEI 4 EP. And the same picture is used...which points me in the direction of the "Collector" EPs compilation. Also a compilation came out in the 70's of Robin Hall and Jimmie Macgregor's "Collector" EPs. I don't know, I may have just muddied the waters.
