Here's the translation of it from Russian, maybe, it will help you to remember it:

He carried two pistols day and night
But was always ready to help a poor widow
He passed the poor by on the road
He robbed only people like Terpin and queen Bess
Brennan had lived on the hills for five years
The footmen and the cavalry couldn't catch him
Somewhere in county Tipperery is the place called Clonmoor
Where Wily Brennan and Bon were found by the troops

Sorry for misspelling of the geographical names.
PS: The exact name of the writer is Clive Griffin, but I can't find his book on the net, only in on-line shops and I need it right now… :/
PPS: Great thanks to everybody for your answers
