Ellen and Peter Zane — she’s the former Tufts Medical Center CEO and he was boss at the bike lock maker Kryptonite — were honored at Rogerson Communities’ annual Welcome Home! fund-raiser. Guests included former Tufts president Larry Bacow, former Sovereign Bank CEO Joe Campanelli, former Partners HealthCare CEO Samuel Thier, actress/producer Christy Cashman, and Yes.Oui.Si founder Olivia Ives-Flores. Rogerson consultant Barbara Quiroga emceed, ably filling in at the last minute for Channel 5’s Liz Brunner, who was busy covering the Marathon bombing aftermath. . . . Because music has a healing power, UpStairs on the Square owners Mary-Catherine Deibel and Deborah Hughes decided not to cancel this week’s chamber music dinner at the Harvard Square restaurant. Pulitzer Prize-winning composer John Harbison premiered his “Gatsby Songs” featuring tenor Ryan Turner and soprano Kristen Watson. The crowd included Harbison’s wife, violinist Rose Mary Harbison, Cantabridgians Carol Monica and Donna Davis, Draper Laboratory’s Peter Wender, and Emmanuel Music CEO Patricia Krol. . . . Along those same lines, ImprovBoston is opening its doors for free Friday to folks looking for a night of much-needed laughter. (ImprovBoston will still happily collect donations for One Fund Boston at the door.) “Laughter is the best medicine we have and we want to make sure people have access and the opportunity to laugh, especially after the week we’ve had,” said managing director Zach Ward.
