tune collection

This site's tune sets were found in September 2007, and disappeared in March, 2017. Despite the "german" in the name, the tunes are mostly part of the standard Irish session repertoire. If you know anything about it, let me know what happened to them, and what I should do with this collection? Meanwhile, I'll just leave them here for anyone that's interested.
