"Horror, Horror y Sexo" in the Bronx

Here's an ad for a live musical stage show titled "Horror, Horror y Sexo" that was performed at the Puerto Rico Theater in the Bronx in 1971 before showings of SINISTER INVASION (one of the four Mexican co-productions Boris Karloff made with Jack Hill in 1968)! A Regency Caribbean production directed by Willy Chevalier, with a libretto by Tony Betancourt, "Horror, Horror y Sexo" co-starred Perla Faith from Nuyorican films such as LA TIGRESA (1970) and NATAS ES SATAN (1975) and Iraida Polanco, who was a busy actress in New York-shot films (BAD LIEUTENANT, RANSOM) and TV shows (LAW AND ORDER, NYPD BLUE) for 15 years prior to her death last year. I wonder if there's a copy of the script at Lincoln Center or elsewhere in the New York Public Library system.
