Priest Bury

The Deaths in 2017 lists under December 18:

Barry Cohen, 82, Australian politician, MP (1969–1990), Alzheimer's disease

Note from his wiki page:

Barry Cohen AM (3 April 1935 – 18 December 2017) 

His name translates into a cryptic combination. “bury priest”/ bury co(together) chicken(cowardice).  So we’ll wait for the next notable Priest to pass away for the next part of this communication.  
Bury Priest... cohen “co hen”... together chicken......afraid

So bridging the April 4 gap using the formula as per usual we arrive at:

Lucille Lortel (December 16, 1900 – April 4, 1999) was an American actress, artistic director and producer.

On investigating her wiki page and those mentioned our investigation reveals the following:

In the course of her career Lortel produced or co-produced nearly 500 plays, 5 of which were nominated for Tony Awards: As Is by William M. Hoffman (April 12, 1939 - April 29, 2017); Angels Fall by Lanford Wilson (April 13, 1937 – March 24, 2011); Blood Knot by Athol Fugard, (born 11 June 1932) Mbongeni Ngema's (born 1 June 1956) iSarafina! ;and A Walk in the Woods by Lee Blessing (born October 4, 1949) .  Marcus Samuel Blitzstein (March 2, 1905 – January 22, 1964);  Bertolt Brecht (10 February 1898 – 14 August 1956) ; Kurt Julian Weill (March 2, 1900 – April 3,1950); spouse  Louis Schweitzer (February 5, 1899 – September 20, 1971); Max Reinhardt (September 9, 1873 – October 30, 1943) ; David Belasco (July 25, 1853 – May 14, 1931); Dame Judith Anderson (10 February 1897 – 3 January 1992); Florence Reed (January 10, 1883 – November 21, 1967) ; Kintaro Hayakawa (June 10, 1889 – November 23, 1973); Danny Kaye (January 18, 1911 – March 3, 1987) ; George Costello Wolfe (born September 23, 1954) ; Eva Marie Saint ( July 4, 1924); Seán O'Casey ( 30 March 1880 – 18 September 1964) ; Eugène Ionesco ( 26 November 1909 – 28 March 1994); Archibald MacLeish (May 7, 1892 – April 20, 1982) ; Edward Franklin Albee III ( March 12, 1928 – September 16, 2016) ; Samuel Barclay Beckett (13 April 1906 – 22 December 1989) ; Murray Schisgal (born November 25, 1926); Adrienne Kennedy (born September 13, 1931) .... 

  and more, to come later.          
   The Tony Award namesake: Mary Antoinette "Tony" Perry (June 27, 1888 – June 28, 1946) ... obviously she needs further investigation.     

Also on April 4 wiki page:

• Anthony Caruso (April 7, 1916 – April 4, 2003) 

 Caruso’s surname re: “car you so...”... jives with the recent “car crash”pattern-cluster.
