So does someone have Margaret Barry's lyrics? (Cheapskate Joe wants it for free!)
By the way, on a website about Jews in Dublin, there was a mention that Briscoe was involved in gunrunning for the IRA during the era of the irish war of independence. It was this act that ultimately brought him to prominence. He was unknown to the British at the time or they would've hanged him.
If there is an earlier version, it probably would be without reference to Briscoe or garbage collecting.
