I'm pretty sure these are the lyrics for the chorus of the song. My scout leader used sing it at camp fire when we went to summer camp. We (the rest of the troop) sang the chorus and he sang the rest. I think it goes something like this :

Oh at McCarthy's Party every one was hearty,
someone hit Maloney on the nose,
With the handle of a broom O'Hara swept the room,
then a row arose there was murder,
Murphy and his cousin paralised a half a dozen,
they hit both swift and hardy,
and a number of the boys will never make a noise,
'cause they're lying in the ould Church yard,
(without they're shirt on...lying in the ould church yard).

If these are correct and you'd like the rest of the lyrics I'll try to get them for you.
Regards,
James.
