In the first Glyndebourne season, in 1934, Nash played Basilio in "Le nozze di Figaro" at the inaugural performance, Pedrillo, and Ferrando in "Così fan tutte". He sang these three roles every year until 1938, adding Ottavio in "Don Giovanni" in 1937. The critic Richard Capell wrote, "Hardly another tenor of his time has sung Mozart with such elegance and at the same time such a minstrel-like effect of spontaneity." Nash also sang in lighter musical stage works, appearing in Carl Millöcker's "The Dubarry" in 1932, and Edward German's "Merrie England" in 1945.
