"The Tar Barrel song was written by one George Unthank and is sung with pride by the girls"

Plus I'd imagine the good folk of Allendale are on the whole proud of the song too. I can't imagine they are quite as insular as the other post seems to suggest they'd be. Don't have personal knowledge of it as such but come from just across the border and here the locals of the various towns tend to be delighted when others take an interest and contribute to festivities etc!
