Ah, another Christmas season is upon us, with all its glorious lights and festivities. “A poor excuse for picking a man’s pocket every 25th of December!” says Ebenezer Scrooge in A Christmas Carol. Don’t be like the downhearted Scrooge. Instead, experience the life-affirming laughs of the season for three performances with The No Script Society Improv in A Scriptless Carol. The rotating 15-member troupe will be mining the audience for ideas to ad-lib about — well, almost anything related to the holidays based loosely on cues from the Charles Dickens classic tale — and audience participation is strongly encouraged. “We’re hoping it’s going to be our biggest, most ambitious show,” says Adam Leonard, an organizer for the three-day production. The No Script Society Improv started at Very Little Theatre shortly before the COVID pandemic. It wasn’t until this past summer (“It took a little longer than I wanted,” Leonard says) that the group returned, but it returned to a packed house at VLT’s Stage Left. “We really love what we’re doing,” he says. “We’re impressed with the people coming out. There’s a hunger for improv.”
