Towards the end of his life I worked briefly with Charles Parker when he was putting on productions of radio ballads at colleges. He did mention other scripts but unfortunately I never got to see them. Coincidentally, I found myself working alongside Ian Campbell in a TV production office just a few years later. Again, even more unfortunately, I never got round to talking to him about the scripts. However, I do see Ian's son David from time to time and I'll be sure to ask him if they are still in existence. As they're not in the Charles Parker Archive they may well be chez the Campbells . . .
