The Irish Rover is a traditional Irish Folk song which tells the story of a magnificent mythical sailing ship travelling from Cork to New York. The narrator is the ships only surviving crew member, and being the only survivor means that everything he tells is so over the top and impossible but that there is no one to contradict him.
The song describes a gigantic ship with "twenty-seven masts", even the Cutty Sark only had 3! a colourful crew and varied types of cargo in enormous amounts. The verses grow successively more extravagant about the wonders of the great ship.
