'Oro Se Do Bheatha Abhaile' and 'What Shall We Do With the Drunken Sailor?' do share a maritime theme at least. 'Oro..' is about the Galway chieftainess Grace O'Malley who is reputed to have preyed on English shipping in the Irish Sea in Elizabethan times. She apparantly visited Elizabeth 1 of England at court and caused a stir as the 'Irish Pirate Queen'.
