Mayor Marty Walsh seemed to enjoy himself at Monday’s Spotlight Spectacular, the annual fund-raising gala for the Huntington Theater Co. The Bryan Rafanelli-produced event, which raised $1 million for the Huntington and its programs, honored Billy Porter, a Tony winner for “Kinky Boots” whose credits also include “The Colored Museum” and directing “Topdog/Underdog.” “Theater saved my life,” said Porter, accepting the Wimberly Award. “I was a little, poor, black, gay kid with nothing. Afterschool programs — angels who stepped in and encouraged my God-given talents — programs like [the Huntington’s] Student Matinee Series, saved my life. I would not be standing here in front of you with all these accolades and titles if that didn’t exist.” He then performed “Edelweiss” from his new album, “Billy Porter Presents the Soul of Richard Rodgers.” Guests included prominent arts and business leaders, including the mayor, Barbara and Amos Hostetter, Alice Hoffman, Ron and Julie Druker, Karen and Michael Rotenberg, Joyce Linehan, Julie Burros, Beth and Carmine Martignetti, and Bob Rosenberg.
