While studying with Borgatti, Nash made his operatic debut in 1924 at the Teatro Carcano in Milan, when he replaced an indisposed tenor in the role of Almaviva in Rossini's "Il barbiere di Siviglia". It was a notable success. After singing at Turin, Bologna and Genoa, Nash returned to England with his wife in 1925. He had developed an Italianate style of singing that remained with him: it was said of him that he sang everything as though it were by Verdi.
