This year, D. Scott Withers did the near-impossible: He gave some real depth to one of musical theater's most famously underwritten roles. Herbie, the love interest of Mama Rose in Arthur Laurents' Gypsy, is as one-dimensional as supporting roles get — perhaps because he's an apocryphal character who replaces the real-life Rose's many lesbian lovers. Whatever the reason, Herbie is a snooze — so long as he's not being played by Withers, who truly brought the guy to life in Phoenix Theatre's production of the famous tuner in March. Withers' big exit scene packed a wallop each night, and it may have been the only time that all eyes weren't on the marvelous Kathy Fitzgerald as his gal pal, Mama Rose.
