Lannigan's Ball mentions "Brook's Academy" as the place where our hero learned to dance. About fifteen years ago, at the start of a huge revival of interest in Irish "set-dancing", an organisation was set up under the same name to run classes, revive old dances, publish material etc.

Mind you, when its sung in Ireland the chorus usually goes "Six long weeks...." rather than three! Maybe we're slow learners!
