"Lady Owen's Delight", in Welsh "Difyswch Arglwyddes Owain" is a Welsh air in G Major. The parts are played AAB. Groves, in the 1911 edition of his Welsh Music says that the first Welsh publications of the melody appear in the works of Blind Parry, where it is included in his first collection of twenty-four 'Arias' (an un-named publication), and in Twelve Airs for One and Two Guitars (c. 1760-65, where the tune appears without a name). A later edition of the latter work (1781) gives the title as "Difyswch Arglwyddes Owne's". The tune here is probably late eighteenth century, a harper's air which survived as a tune for songs. It was also printed in Bingley's North Wales...delineated from two excursions, vol. 2 (1804) and Williamson's English, Welsh, Scottish and Irish Fiddle Tunes (1976).
