This was a BBC Wales production in Welsh of Saunders Lewis's Play "Brad" (betrayal) performed entirely in Welsh. The video of this production was amongst my late father, Dillwyn Owen's possessions. He played the part of Blumentritt in the production. I have been unable to work out exactly when it was broadcast, but I suspect it was around 1968. The videotape had a few areas where no signal was present, but the soundtrack continues throughout, and I trust these little glitches won't spoil this little piece of Welsh history.
