Beginning in 1896 and continuing for ten years, Barrington played in a series of very successful musical comedies under the management of George Edwardes at Daly's Theatre, specialising in comic portrayals of pompous rulers or other persons of authority. One of the most popular features of his performances was his insertion of topical songs, or verses of songs, into these musical comedies. After leaving Daly's he continued to appear in musical comedy roles and performed in music hall. He also essayed a few Shakespeare and other dramatic roles and appeared in a few silent films. His career ended in 1918, after which he suffered a stroke and lived the last few years of his life in poverty.
