I've been asked over the years to put a few songs up on my own website by a few DAGDAD aficionados, so if you want to you can download a few and see what you think as to the limitations or otherwise of the tuning. Click HERE.
The John Martyn song, "I Don't Want To Know" is in DAFDAD, and "Black Is The Colour" is in Standard. The rest are in DAGDAD.

All the best.
