Some context: O'Neill was born in a hotel, the Barrett House, at Broadway and 43rd Street, on what was then Longacre Square (now Times Square). A commemorative plaque was first dedicated there in 1957. The site is now occupied by 1500 Broadway, which houses offices, retail, and ABC Studios. He was the son of Irish immigrant actor James O'Neill and Mary Ellen Quinlan, who was also of Irish descent.
After suffering from multiple health problems (including depression and alcoholism) over many years, O'Neill ultimately faced a severe Parkinsons-like tremor in his hands which made it impossible for him to write during the last 10 years of his life; he had tried using dictation but found himself unable to compose in that way. While at Tao House, O'Neill had intended to write a cycle of 11 plays chronicling an American family since the 1800s. Only two of these, A Touch of the Poet and More Stately Mansions, were ever completed. As his health worsened, O'Neill lost inspiration for the project and wrote three largely autobiographical plays, The Iceman Cometh, Long Day's Journey into Night, and A Moon for the Misbegotten. He managed to complete Moon for the Misbegotten in 1943, just before leaving Tao House and losing his ability to write. Drafts of many other uncompleted plays were destroyed by Carlotta at Eugene's request.  O'Neill died in Room 401 of the Sheraton Hotel (now Boston University's Shelton Hall) on Bay State Road in Boston, on November 27, 1953, at the age of 65. As he was dying, he whispered his last words: "I knew it. I knew it. Born in a hotel room and died in a hotel room." Dr. Harry Kozol, the lead prosecuting expert of the Patty Hearst trial, treated O'Neill during these last years of illness. He also was present for O'Neill's death and announced the fact to the public.  O'Neill is interred in the Forest Hills Cemetery in Boston's Jamaica Plain neighborhood.  In 1956 Carlotta arranged for his autobiographical play Long Day's Journey into Night to be published, although his written instructions had stipulated that it not be made public until 25 years after his death. It was produced on stage to tremendous critical acclaim and won the Pulitzer Prize in 1957. This last play is widely considered to be his finest. Other posthumously-published works include A Touch of the Poet (1958) and More Stately Mansions (1967).  The United States Postal Service honored O'Neill with a Prominent Americans series (1965-1978) $1 postage stamp.

Some context: The Blockheads are an English rock and roll band. Originally fronted by lead singer Ian Dury as Ian Dury and the Blockheads, the band has continued to perform since Dury's death in 2000. Current members include Derek Hussey (vocals), Chaz Jankel (keyboards and guitar), Norman Watt-Roy (bass), Mick Gallagher (keyboards and piano), John Turnbull (vocals and guitar) and John Roberts (drums). There is rolling line-up of saxophonists that includes Gilad Atzmon, Terry Edwards or Dave Lewis and from time to time, the original sax player, Davey Payne.
In 1974 Radio Caroline's Ronan O'Rahilly set up the pop group The Loving Awareness Band, comprising John Turnbull (guitar) and Mick Gallagher (keyboards) both formerly of 1960s psychedelic rock band Skip Bifferty with the session musicians Norman Watt-Roy (bass) and Charlie Charles (born Hugh Glenn Mortimer Charles, Guyana 1945) (drums). In 1976 The Loving Awareness Band released their only album, Loving Awareness (ML001), on O'Rahilly's label More Love Records. The album has appeared on CD more than once, although these reissues have been sourced from a mint vinyl pressing rather than from the original master tapes.  The Loving Awareness Band broke up in 1977 and Watt-Roy and Charles joined a new band being formed by Ian Dury, who had begun writing songs with pianist and guitarist Chaz Jankel (the brother of noted music video, TV, commercial and film director Annabel Jankel). With Jankel fashioning Dury's lyrics into number of songs, the two began recording with Charles, Watt-Roy, Gallagher, Turnbull and former Kilburn and the High Roads saxophonist Davey Payne. An album was recorded, but was of no interest to major record labels. Next door to Dury's manager's office, however, was the newly formed Stiff Records, a perfect home for Dury's maverick style.  The band was invited by Stiff to join the "Live Stiffs Tour", and the band Ian Dury and the Blockheads was born, with the name ostensibly taken from the song of the same name which portrayed a drunken Essex Untermensch stereotype:  The tour, which also featured Elvis Costello and the Attractions, Nick Lowe, Wreckless Eric and Larry Wallis, was a great success, and Stiff launched a concerted Ian Dury marketing campaign.
