My father sang this song years ago and he was never sure of the lyrics even then, they have probably become corrupt over the years.
It goes something like:
Oh, Brian O'Linn was a scotsman born
His legs they were long and his feet they were scorn
with his belly gone in and his eyes gone out,
I'm a hop-a-gone beauty says Brian O'Linn
With your rantin' and and roarin'
ogger and and boarum
stockermen, soldiers,
butchers and barbers
hedgey-me-wedgemey gougin' pin
we'll wallop them all says Brian O'Linn

Any info on the title or spelling of the name to allow me to search it more successfully would be most appreciated.
Thanks!
