He's the author of songs recorded by Frank Sinatra, Sarah Vaughan and Perry Como, but right now Sid Frank is concentrating on his playwriting. As such, seven of his one-acts are currently on view at Off-Off Broadway's Studio Theatre on West 42nd Street. Previews began May 24 for an opening June 15. Under the umbrella title "Kosher Franks," the plays promise to put forth the author's "comically skewed world view" on family, love and life. Plays include The Watercolorist; Honeysuckle, Crinoline and Ronnie Feldman; The Bad Fashion Designer; Flying Lesson; Who The Hell is Abner Bell?, Alice is Dead and I Want The Job.

Barbara Bonilla, Chris Boyd, Michael DeNigris, David Sussman and Leslie Wheeler comprise the cast of Kosher Franks, which is directed by John Morrison. Designing the evening are Neil Prince (set), Diane Clayton (costumes) and Michael Kimmel (lighting).

Songs by Frank include the 1951 gold record (for Johnny Ray), "Please Mr. Sun," as well as "There Must Be Some Mistake" and "I Can Read Between The Lines."
