Yes, Tegwyn 'Pan Celt' Williams is from Llanelwy. I bumped into him last year when Yr Eisteddfod was in Ynys Mon, and we were staying across the bridge in Bangor. I think the time before that was when he became a bard, but I can't remember which Eisteddfod that was at - it may have been Bala.
He and his wife, Margaret, have been associated with the Pan Celtic for a good number of years, and ensure a high profile for the Welsh entry in the Celtafis by having the voting for it on television and radio. They always take a good number of performers and also people who go along for the pleasure of attending the Pan Celtic.
The Pan Celtic is back in Kerry again, albeit in Tralee, rather than Killarney, where I first met Tegwyn and Margaret many years ago. They also arranged a bit of a musical trip for musicians from the Isle of Man to North Wales - but that's also more years ago than I'd care to remember!
So nice to think of the other Tegwyn, too, arising out of this thread on Meic Stevens.
Pob hwyl,
