My folks used to sing that song...if it's the same one...only the chorus line read He rambled til the butchers cut him down... The only verse I remember is

He rambled into an Irish wake, one fine St. Patrick's night.
They asked him what he'd have to drink. Oh, they meant to treat him right.
But just like the old Kilkenny cats, their backs began to arch
When he asked for an orange phosphate on the 17th of March.
Oh didn't he ramble...etc.

But maybe it's not the same song...I don't remember a goat having anything to do with it...
