1970s
Patrick directed a production of his own play, The Richest Girl in the World Finds Happiness, at La MaMa in 1970. He directed his own plays, Valentine Rainbow at La MaMa and The Golden Circle at 119 Spring Street, both in 1972.
Patrick directed holiday shows at La MaMa in 1971, 1972, and 1974. The 1971 production was called La MaMa Christmas Show, the 1972 production was Play-by-Play, and the 1974 production was Play-by-Play: A Spectacle of Ourselves. In 1973, he directed Paul Foster's Silver Queen, which featured music by John Braden, at La MaMa.
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 production was instantly successful and was signed for the West End and other international productions. 1974 was the first season of gay theatre in the United Kingdom, to which Patrick contributed three plays. His play Cleaning House was produced in California during the summer of 1974.
A 1974 Boston production of The Haunted Host was the first time Harvey Fierstein appeared on the professional stage as a man. Years later, Fierstein included a recording of Patrick's monologue "Pouf Positive" on his compact disc This Is Not Going to Be Pretty. "Pouf Positive" was also filmed by Dov Hechtman in 1989.
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. She reprised her role in the 1979 CBS production of the play.
Patrick traveled widely, from Anchorage to Cape Town, to see productions of Kennedy's Children. For ten years, he visited high schools and high school theatre conventions nationwide on behalf of the International Thespian Society.
In 1976, Marlo Thomas commissioned Patrick to write My Cup Ranneth Over for her and Lily Tomlin. Although they never performed in the play, it would become Patrick's most produced work.
Patrick co-wrote Da Nutrcracker in Da Bronx with Jeannine O'Reilly and Paul Foster; the production was directed by Powell Shepard at La MaMa in 1977.
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.
