I was poking around a hymn website when I noticed this:
The main tune is apparently named after Williams’ home town of Llanfairpwllgwyngyllgogerychwyrndrobwllllandtysiliogogogoch. In English, the name means “church of St. Mary in the hollow of white hazel near the rapid whirlpool of the Church of St. Tysillio by the red cave.”
If this is a joke it is funny, if it is real it is even funnier! (original link, warning MIDI)
