Nice selection, Chris. Pity you weren't here on 3 November - we're running a Plygain workshop.

Re: Caneuon Ffydd, there are just two versions - one 'Old Notation' and the other 'Tonic Sol-ffa'. I have the Old Notation and it has no ready-made guitar chords (as you probably know). I presume it is likewise for the Sol-ffa. I don't think any of the standard hymnals have chords so it's a matter of working them out from the notation I guess.

BTW - do you have the re-issue of Caneuon Traddodiadol y Cymry (Traditional Songs of the Welsh)? Another Cyhoeddiadau Gwynn book that came out last year. Very handy collection.
