Datblygu - “Ugain I Un” (Twenty to One). No idea what’s being sung. I had a brief flirtation with Welsh indie when I was a youngster, though it was mainly the contemporary groups (Super Furries, Gorky’s).

One notable exception was Datblygu, whose output was mainly in the 80s. About 10 years ago, I got their Greatest Hits on mail order. Two of those songs I still have - “Y Teimlad” (which was later covered by Super Furry Animals), and “Merch Ty Cygnor” (itself a cover). Neither is on YouTube, but I did find the above, which I think is pretty good, even if I don’t understand a word.
