The Furys Chronicle: The Furys Chronicle is a sequence of five novels, published between 1935 and 1958, by James Hanley (1897–1985).  The main setting is the fictional, northern, English town of Gelton, which is based on Liverpool, where Hanley was born, and involves an Irish Catholic family of seafarers, similar to Hanley's own.  The action takes place between 1911 and 1927.  The first novel in the series, "The Furys", was Hanley's sixth novel.

Troubles (novel): Troubles is a 1970 novel by J. G. Farrell.  The plot concerns the dilapidation of a once grand Irish hotel (the Majestic), in the midst of the political upheaval during the Irish War of Independence (1919–1921).  It is the first instalment in Farrell's acclaimed 'Empire Trilogy', preceding "The Siege of Krishnapur" and "The Singapore Grip".  Although there are similar themes within the three novels (most notably that of the British Empire), they do not form a sequence of storytelling.

The show was staged by Allan Dinehart with dance numbers by Larry Ceballos.  The production was designed by John Held, Jr.  It ran for 224 performances, closing in February, 1927.  The cast headlined Lew Brice, Roy Atwell, Betty Compton, Charles Butterworth and the Eddie Elkins Orchestra The New York Times review called it a "witty, ingenious and sophisticated evening of fun-making, it made up in its abundant humor for more than it lacked in some other departments."  The other departments referred to were lack of chorus girls and opulent settings.

J. G. Farrell: James Gordon Farrell (25 January 1935 – 11 August 1979) was a Liverpool-born novelist of Irish descent.

James Hanley (novelist): James (Joseph) Hanley (3 September 1897 – 11 November 1985) was a British novelist, short story writer, and playwright of Irish descent.  He published his first novel "Drift" in 1930.  The novels and short stories about seamen and their families that he wrote in the 1930s and 1940s included "Boy" (1931), the subject of an obscenity trial.  Hanley came from a seafaring family and spent two years at sea himself.  After World War II there was less emphasis on the sea in his works.  While frequently praised by critics, Hanley's novels did not sell well.  In the late 1950s, 1960s, and early 1970s he wrote plays, mainly for the BBC, for radio and then for television, and also for the theatre.  He returned to the novel in the 1970s.  His last novel, "A Kingdom", was published in 1978, when he was eighty.
