I think that this is one of those songs where you're going to find 50 different alternate spellings of kilgrane (Kilgrain, Kilgraine?) and a better bet is to search the digitrad for @hunting and see what come up.
I had given up on finding lyrics for "Johnny O' Bradis Lea" but recently found it with a topic search, titled "Johnny of Braidsley".
Go figure. Anyway, I'm pretty sure this one is in the digitrad.
And anyone else following this thread. Casey Neill Trio is a damn fine band. Buy the CD's make thme rich. They deserve it.
