If Jerry Springer can be an opera, why can’t Monica Lewinsky be a Broadway musical? Now she will be: “Monica! The Musical” will get its first reading at the Manhattan Theatre Club on May 7. “Its creators, hope that the reading will lead to a stage berth here in New York, where it would join unlikely post-post-ironic musicals such as Debbie Does Dallas, Urinetown and the new Zanna, Don’t!” Some sample lyrics? “I feel I’ve lost my head,” sings young Bill. “Don’t look too hard for you will find it / Beneath my dress of red,” responds the siren.”
