The Delaware Theatre Company’s annual gala “Play A Part” took on a special significance this year, as the renowned theater celebrates is 30th anniversary. The DTC isn’t just local theater any more. Since Executive Director Bud Martin joined the DTC three years ago, several musical and dramatic performances have sold out, and many shows headed to New York for Broadway and Off Broadway runs. February 6th’s “Play a Part,” with two-time award winner and vocalist Christine Ebersole on stage, once again drew large numbers of patrons. The one-night performance was preceded by an elegant cocktail and dinner hour at the nearby Riverfront Market.
