Glen were inspired by Peggy Dorgan at midfield in the second half, equalised with five minutes to go, and forced the match to a replay.
In the replay, things looked bad for Celtic when Glen Rovers led by four points with ten minutes to go, Una O'Connor retired with a head injury and Celtic substitute Kit Kehoe celebrated her arrival on the field by first-timing the ball in the direction of her own goal.
Una O'Connor scored three goals and Mary O'Keeffe two more as Celtic claimed the Jubilee Cup and were allowed to keep it permanently.
Agnes Hourigan wrote in the Irish Press: The main factor in Dublin’s victory was their solid defence which was built around All-Ireland star Alice Hussey who gave a memorable display at centre back never relaxed its grip on Deridre’s attack and was as effective against the wind after the interval as it had proved in the first half.
Though closely marked from the start, she was always the obvious threat to Deirdre’s chances, and her first half scores laid the foundations of victory.
