“ Callcott's 'Peace to the souls of the heroes'; Stevens's glee, 'To be gazing on those charms,' and some songs, duets, catches, and rounds. The chief vocal writers of the day including Callcott, Crotch, Spofforth, Dr. Clarke, and Stevenson contributed new works to the programmes, and Italian music was added. In 1793 Mme. Dussek and Miss Poole (afterwards Mrs. Dickons) joined the vocalists, and the brothers Leander, then the most celebrated horn-players in Europe, were added to the little band. ”
