Having been born in Belfast, and having lived in Bangor, Northern Ireland for many years, I counted the number of towns in North America with these names. This was a few years ago now, but I seem to remember there having been something like 13 towns in the USA called Bangor, and about 6 towns called Belfast. With the large number of Scots-Irish and Irish-Americans in the USA, would it be surprising if this town wasn't named after the town of Bangor located in Northern Ireland? The only tune I can think of that mentions Bangor refers to the town in Wales. Either way, perhaps one of these towns deserves mention in the article.
