My Uncle, Willie Gillespie, wrote this song. Dr. Johnston was the only one around with a car to get the arms to Dungloe - Rosses. The version that is sung mostly (Clancy Brother version) contains many wrong names. There is no railway bridge. The correct words are the Reelin Bridge, which is over the Reelin River. There was no Brannigan's corner. The correct place is Brocagh, which is the near by village. Dr Johnston lived in the town of Stranorlar. The correct words to the song can be found FinnValley.com/people/williegillespie
