One I haven't heard but once is "Pride of Petrovar" -- which is Irish, regardless. IMHO rebel songs in the US can be okay, especially if the crowd is happily in their cups and willing to roar along with the chorus, but I would certainly think twice about singing them in Ireland.

From Stan Rogers, "Fogarty's Cove" "Northwest Passage" or "McDonell on the Heights" are good. Others you might think about are "Night Guard" "The Idiot" and "Barrett's Privateers" will get even a sober crowd wound up.

Stuff from Schooner Fare, such as "Mary L. McKay" "Mad Jack" and "Boats of Stone" might also go over.

Personally, I think it's best to do fifty things well than three times that number in a mediocre way.

Good Luck. May the Stage Collapse!
