Mainstream theatergoers became acquainted with him in 1981, when he partnered with composer Henry Krieger and director Michael Bennett to write the book and lyrics for the hit Broadway musical Dreamgirls, about an African-American female singing trio.
[3] His early off-off-Broadway plays, other than those noted above, included: The title character in Why Hanna's Skirt Won't Stay Down has been described as representative of the crudeness, exuberance, decadence and profundity of the movement and the period.
[15] In 1970, Eyen had his biggest commercial success to date with The Dirtiest Show in Town, a satirical response to, and example of, the period's plays depicting nudity and sexual situations.
The Dirtiest Show in Town initially ran at the Astor Place Theatre for two seasons, with later runs both off-Broadway in New York and in London's West End.
"[3] In 1973, Eyen co-wrote the book for and directed one of Broadway's most notorious flops, the Paul Jabara disco musical Rachael Lily Rosenbloom (And Don't You Ever Forget It), which closed after seven previews.
[citation needed] In 1978, Eyen earned an Emmy Award nomination for writing Midler's first television special, Ol' Red Hair is Back.
"[7] In 1980, Eyen directed a film version of The Dirtiest Show In Town for Showtime, making it the first made-for-cable television movie.
[22] In 1976, he appeared in Rosa von Praunheim's documentary film about New York's SoHo theatre and arts scene in the 1970s, Underground and Emigrants.
[25] A year later, the project caught the interest of Broadway director-producer Michael Bennett, who asked Eyen to direct a workshop production of Big Dreams, as the musical was then named, featuring Ralph, Loretta Devine, and gospel singer Jennifer Holliday as Carter's replacement.
The original cast album won Eyen a Grammy Award as lyricist, and one of the show's songs, "And I Am Telling You I'm Not Going", as sung by Holliday, became a hit.
[citation needed] In 1984, Eyen sought to duplicate his Dreamgirls success with Kicks: The Showgirl Musical, a collaboration with composer Alan Menken about the Rockettes during World War II.
In 1993, Eyen posthumously received the Jerome Lawrence and Robert E. Lee Theatre Research Institute Award from Ohio State University, where his papers are archived.
