Perkins School for the Blind held its annual gala last week, raising more than $1.6 million for the academy in Watertown. Corinne Grousbeck, wife of Celtics owner Wyc Grousbeck and the chair of the Perkins board, was at one point joined onstage (above) by her son Campbell, a Perkins student who graduates in June. (Together, they urged the crowd to match the $100,000 grant from the Grousbeck Trust to provide technology to Perkins grads.) Grousbeck co-chaired the event with “Friends” producer Kevin Bright and Schawbel Corp. CEO Bill Schawbel, while Sly Stone’s backing band, the Family Stone, entertained the crowd and Lenny Clarke yukked it up as the evening’s auctioneer. The crowd included new Perkins CEO Dave Power, Tom and Elena Matlack, Joe and Kathy O’Donnell, Simone and Ted Winston, Dunkin Brands CEO Nigel Travis, Celtics alums Tommy Heinsohn and Jo Jo White, Emerson president Lee Pelton, and former Sox infielder Jed Lowrie, in town with the Oakland A’s.
