The typescript consists of pages from the original script, [1962], transmitted on BBC TV on St David's Day 1962 (ff. 5-16, 20-21, 42-51), interspersed with revised sections, [1979], for an abortive stage version (ff. 17-19, 22-41, 52-56), and the new Preface for the published volume, April 1980 (ff. 2-4). The correspondence consists of nineteen letters, April-October 1980, including copies and drafts, mostly between Saunders Lewis, Christopher Davies, Sir Alun Talfan Davies and Glyndwr Williams, brother of Llywelyn Williams. A cutting of Clive Betts' article, 'Saunders Lewis publishes play BBC abandoned' (Western Mail, 1 December 1980, p. 9), is on f. 82. The 1962 and 1980 versions of the play both appear in Dramâu Saunders Lewis: Y Casgliad Cyflawn, Cyfrol 2, ed. by Ioan M. Williams (Cardiff, 2000), pp. 273-414.
