The result of the collaboration was Dynamite Tonite, an anti-war satire that opened in 1964 at the Actors Studio in Manhattan, with a cast that included Alvin Epstein and Gene Wilder.

[1][2] Weinstein's notable works include the long-running 1961 off-Broadway satire The Red Eye of Love, about an all-meat department store,[1] and an adaptation of Ovid's Metamorphoses, originally present at the Yale Repertory Theater in 1969[3] and subsequently produced on Broadway in 1971.

[4] With a new rock/blues score provided by his then-collaborator, composer Tony Greco,[5] Ovid's Metamorphoses debuted at Gian Carlo Menotti's Spoleto Festival dei Due Mondi in 1973.

Weinstein collaborated with Greco on four subsequent original theatrical works: The American Revolution, which premiered in 1973 at Ford's Theatre, in Washington, D.C., directed by Paul Sills; a musical of Weinstein's translation and adaptation of García Lorca's poetry titled Gypsy New York, presented at Cafe La Mama in 1974, produced by Gaby Rodgers, with art direction by Larry Rivers; Lady Liberty's Ice Cream Cone directed by Barbara Harris in 1974 at the New York Cultural Center; and the San Francisco A.C.T.

[1][6] Weinstein also provided the libretto for Bolcom's Medusa: Monodrama for Dramatic Soprano and String Orchestra which was premiered by conductor Dennis Russell Davies leading the Stuttgart Chamber Orchestra in May 2003,[7] and the text for the composer's "music theater opera"[8] Casino Paradise, which was presented by American Music Theater Festival (AMTF) in Philadelphia in 1990, and, in a revamped version, by Lincoln Center's "American Songbook" series in 2005.

[10] Weinstein wrote the lyrics to Shlemiel the First (1994), an adaptation of the Chełm stories of Isaac Bashevis Singer set to klezmer music, and Punch and Judy Get Divorced a 1996 theatre piece by post-modern choreographer-director-writer David Gordon and composer Edward Barnes, both of which were originally produced by Robert Brustein's American Repertory Theater in Cambridge, Massachusetts, and the American Music Theatre Festival in Philadelphia.
