[2] Patrick stopped in New York City on his way back to Roswell from Maine and happened upon the Caffe Cino, the first Off-Off Broadway theatre, on September 14, 1961.

He stayed in New York, working for free at the Caffe Cino, La Mama ETC, and other early Off-Off Broadway theaters in any capacity, and supported himself with temporary typing jobs while observing and participating in dozens of productions, including Lanford Wilson's So Long at the Fair.

[6] In November 1965, Patrick was production coordinator for BbAaNnGg, a benefit to raise money for electrical work at La MaMa's 122 Second Avenue theatre, which included plays, spoken word, performance art, and film by many prominent Off-Off artists.

Also in 1969, his play Camera Obscura was produced on PBS, starring Marge Champion, and was chosen to be in the well-known playwright revue "Collision Course".

[14] In 1973, Patrick's Kennedy's Children had an obscure opening in the back of a London pub theatre called the King's Head, in Islington.

The 1975 Broadway production of Kennedy's Children earned Shirley Knight a 1976 Tony Award for Best Performance by a Featured Actress in a Play.

T-Shirts was first produced in 1979, starring Jack Wrangler, and was later chosen as the opening piece in the anthology Gay Plays: A First Collection.

Patrick has also ghostwritten several screenplays for film and television; contributed poems and reviews to Playbill, FirstHand, and Adult Video News; and had his short stories published in anthologies.

Patrick later published his memoir Film Moi or Narcissus in the Dark and the plays Hollywood at Sunset and Michelangelo's Models.

[19] In 2010, he published a DVD of his lecture "Caffe Cino: Birthplace of Gay Theatre" and two books of poems, A Strain of Laughter and Bitter with the Sweet, with Lulu.com.

In 2013, he was brought back onto the stage by young Los Angeles underground theatre artists, appearing as a reader, singer, and actor.

In March 2014, he gave a solo performance about his career entitled, "What Doesn't Kill Me...Makes a Great Story Later," which featured a capella renditions of many of his original songs.
