NOTE: The song at the end "I Am Stretched on Your Grave" is a translation of an anonymous 17th-century Irish poem titled "Táim sínte ar do thuama". It was translated into English several times, most notably by Frank O'Connor. It was put to music by musician Philip King in 1979. Two verses of that song were blended with a custom written verse and sung by Ramon Leon Del Mar and added to the end of this video before it was posted to cyberspace.
