"The Walls of Liscarroll (in Gaelic Ballaide Lios-Cearbaill) also known as "Andy Hehir's Jig" or "Lads on the Mountain” is an Irish double jig in D Mixolydian, D Dorian or E Dorian. This version is in D Dorian but Williamson gives it with the B part in D Major. The parts are played AABC, AABB or AABB’. The town of Liscarrol, meaning ‘Fort of Cearull,’ is located in county Cork, near the border with Limerick about halfway between the cities of Limerick and Cork and dates from the early Middle Ages. There is a ruined castle there to which the title may refer or it may perhaps reference a battle that occurred at Liscarroll in the 17th century. Williamson (1976) reports that one of the lords of the castle, Sir John Purcell of Hightort, “is remembered for his feat of slaying, when armed only with a carving knife, eight armed robbers as they forced their way into his bedroom”.
