Mayo won the Connacht championship for the fourth successive time and advanced to the All-Ireland semi-final against Kerry.
With Mayo behind in injury time, Langan was switched to full-forward against the great Kerry full-back Paddy Bawn Brosnan.
They completed their second consecutive All-Ireland title by beating Meath by five points in the final, with Langan netting another fine goal.
