I've seen many college productions in my time, but last night under a red full moon, I saw the funniest of all. The Davidson College production of Scapin, directed by reigning Theaterperson of the Year Scott Ripley, is a laugh riot for young and old. Don't wait for a full review — the fun will be over by the time my next Performing Arts column appears in print. A prodigally gifted cast, spurred on by Ripley, heaps layers of commedia dell'arte shtick upon an Andrei Belgrader/Shelley Berc adaptation that already plays fast and loose with the original Molière script. Blues and rap travesties by composer/lyricist Rusty Magee top off the zaniness. Or at least they stand shoulder-to-shoulder with the absurd pajama-party concept that frames this insane romp. Tonight the audience is invited to attend the 7:30 p.m. performance in pajamas. Those who do are rewarded with free milk and cookies at intermission! On Friday and Saturday, also at 7:30 p.m., normality returns, and the brief run ends Sunday with a 2 p.m. matinee. Upstairs at the Sloan Music Center in Tyler-Tallman Hall.
