Dave Kincaid's recordings, as mentioned above are very good. He does thorough research and produces a very handsome product. If you have the opportunity to see him live, don't pass it up. Click here for David Kincaid's webpage.

No Irish Need Apply by The Gallant Sons of Erin is very good too. The webpage for their recording is The Gallant Sons of Erin.

To confuse matters further, Folk-Legacy Records issued Irish in America: A Musical Record of the Irish People in the United States, 1780 - 1980 in 2000. That CD has 2 Irish songs from the U.S. Civil War, "The Irish Volunteer" and "Pat Murphy of the Irish Brigade" plus an Irish song from the Revolutionary War, "The Sons of Liberty." The webpage for that CD is Irish in America. It received some very good reviews, which you can read at that site.

The disclaimer should read that both Dave Kincaid and some of The Gallant Sons of Erin are friends of mine, and my friend Bob Conroy and I are the singers on Irish in America.   

Above, DannyC asked about a ballad known as "The Seven Irishmen." That's an old broadside ballad very closely associated with the late Irish traditional singer Joe Heaney. I second the suggestion above that Oliver John "O.J." Abbott was the fountain source of "By the Hush." The late Frank Harte sang "By the Hush" and "The Plains of Waterloo," another song recorded by O.J. Abbott, an Ottawa Valley lumberman and a very important Canadian traditional singer. Virtually everyone in Ireland would've had those songs through Frank and Frank would have to have heard them sung by Mr. Abbott.

All the best,
Dan Milner
