The Battle of Ben Burg is good; it's a Tommy Makem.

As for Protestant and Catholic Irish rebels: Roger Casement, Wolfe Tone, Munro, Henry Joy McCracken, Robert Emmett -- all Protestant, and just a very few names indeed out of many.

I heard a song about it; I have it somewhere. "So here's to all those brave Protestant men/Who gave their lives to free our land./All the people sang their praises then/Those brave United Irishmen." Geez, the old mind's goin' when you can remember the chorus and not the title or group!
