Original Off-Broadway Cast, 2016 (Ghostlight) (3 / 5) Here’s a musical comedy about the porn industry, created by the New York-based theater company The Civilians, with music and lyrics by Michael Friedman (Bloody Bloody Andrew Jackson, Fortress of Solitude, Love’s Labours Lost) and a book by Bess Wohl.  One of the best things about the show is its title, which strikes just the right tone of light humor and sweet naughtiness that’s skillfully maintained almost throughout the proceedings, despite the fact that so much of the content is, indeed, pretty filthy. Song titles include “Waiting for Wood,” “Fuck The World,” and “Squirting 101,” and here’s a sample lyric from the opening number: “Most girls give blowjobs to guys they barely know at college parties.” Although the controversial “Parental Advisory: Explicit Lyrics” label is not affixed to this recording, it applies in spades — but honestly,  why would anyone who decides to purchase the cast album of a show about “adult entertainment” expect anything else? Some of the melodies Friedman created for this unusual project are very tuneful, but a salient feature of the show — some would say its main problem — is that many of the quotes of the porn actors, directors, and producers seem to have been set to music practically verbatim, with only a little modification and a few rhymes and repetitions thrown in to make them more lyric-like. As a result, significant stretches of the score sound prosaic, and often there’s a sense of too many words having been crammed into each measure of music. Still, there’s a lot of illicit, edgy fun to be had here, thanks in no small part to the perfectly gauged performances of a talented cast: John Behlmann as “Fredo/Jimmy Wood,” Lulu Fall as “Dana,” Alyse Alan Louis as “Becky/Taylor,”  Luba Mason as “Georgina Congress,” Maria-Christina Oliveras as “Carrie/Holly Donovan,” Steve Rosen as “Sam Speigel/Jeff/Oscar Gerhard,” Marrick Smith as “Bobby/Dick,” and Jared Zirilli as “Nick Harding.” — Michael Portantiere
