Shortly after the Bloody Sunday shootings in 1972 , Edgar collaborated with six friends ( Tony Bicat , Brian Clark , Howard Brenton , Francis Fuchs , David Hare and Snoo Wilson ) who pretended to be on a walking holiday and booked an isolated country cottage for a week where they sat down and wrote a play together . They took what later came to be termed the " firing squad " approach to playwriting . In a firing squad one member of the party has a blank round , and since no member knows who this is none of them need assume responsibility for the killing . Edgar and his friends tried to write in a style as similar to the others as possible so none of them need take responsibility for his contribution to the play . The result was '' England 's Ireland '' ( 1972 ) , an episodic look at the history of the British in Northern Ireland with different episodes shown from different perspectives . This received its world premiere in 1972 at the hands of the Shoot Theatre Company at the Mickery Theatre , Amsterdam , and later the same year transferred to the Round House Theatre in London
