In his last year, the great Irish dramatist Sean O'Casey was recorded by his wife Eileen as he talked, remembered and, above all, sang. Music meant a great deal to a man brought up in the tradition of melodrama and music hall, and his plays are full of it. Ann Mann explores the music of O'Casey with his children Shivaun and Breon, Professor Katherine Worth, actor Niall Buggy, composer Mark-Anthony Turnage and librettist Amanda Holden, who are making an opera out of O'Casey's play The Silver Tassie and the previously unbroadcast tapes. Singer Lynda Richardson. Accordionist Barry Dix. Pianist Simon Joly. Piper Tommy Sands. Producer Piers Plowright
