Former “Saturday Night Live” player Colin Quinn, who’s in town to film “Grown Ups 2,” did some surprise stand-up Sunday night with local guys Joe List and Gary Gulman. While there, the group posed for a shot with Comedy Studio owner Rick Jenkins. Speaking of “Grown Ups 2,” the Adam Sandler movie was scheduled to film on Ocean Avenue in Marblehead on Monday. The crew should be there for much of the week. . . . About 50 people showed up for a talk hosted by the Great Fenway Park Writers Series over the weekend — even though the event was held in Chicago. It was mostly fans on the road and Windy City-based Red Sox supporters who listened to Boston great Rico Petrocelli, announcer Joe Castiglione, fourth-generation season-ticket holder Donna Eden Cohen, and Red Sox CEO Larry Lucchino share ballpark memories to celebrate Fenway’s 100th anniversary.
