In 2007 when comic 445 was posted, a guy recorded a version of 'O Buddy Roy'. It seems to be available on his web page. I think it would fit in with the original compositions made now. Although, even it is available on his page, it might be a good idea to ask his permission to link to it, just to be sure he doesn't mind.

His rendition of the song was received very well on the forum, so by request he recorded two other Elan's songs, 'Won't you come leave the inn with me' and 'Bluff the stupid ogre'. Unfortunately those are not available on his web page.
