Every year Theatr Cymru was heavily involved with the National Eisteddfod and the one at Carmarthen was particularly heavy as the company mounted 3 full scale productions. “Y Pypedau”, “Nia Ben Aur” and the main pageant, “Dewin y Daran”. The last two were staged specially for performance in the Old Pavillion. “Dewin y Daran” told the story of the Rebecca riots. The two illustrations were for back projections. As the screen was so large: 30’ x 16’ it was covered by 3 pairs of carousel projectors, enabling, smooth cross fades.
