Hen Tŷ Coch

This is clearly a variant of the tune Tŷ Coch, and apart from a few small variations, is the minor version of that tune. Its title suggests this is in fact is the older and original tune, though it may be that it just sounds older. I've only put the melody here as the best accompaniment is a simple drone following the chords. Importantly this is harmonised differently to Tŷ Coch, which is based around G major and A minor, whereas this is based around G minor and F major.
