then click "downloads" and download the guitar pro file of songs called "merrily kissed the quakers wife" and " troubadour".
The first one is just his own version of this irish song, the second one is composed by himself.
Maybe there are also some more songs with this tuning, but these are the ones I know.
By the way check out the song:"Waldviertler Nächte" I really like this melody, especially when he plays it live, where it sounds a lot better.
