First, we love Nancy Opel. The frisky singing comedienne all but stole Honeymoon in Vegas from Rob McClure, which can’t have been easy. Her Yente considerably enlivened the goyische Alfred Molina revival of Fiddler on the Roof, and her Dickensian Penelope Pennywise was one of the few enjoyable things about Urinetown. She surely deserves a musical of her own. And she deserves a better one than Curvy Widow.
