the stage

A Little Light Music. Colonial Theater. A new Stephen Sondheim musical, based on Ingmar Bergman's Smiles of a Summer Night. Producer Harold Prince says it's nostalgic but erotic, whatever that means. Til Feb. 10.

Master Builder of Ibsen. Publick Theater, 1175 Soldiers Field Road, behind the Stadium. Til Feb. 17.

Richard III. Theater Company of Boston, opening Saturday at 8 at the Church of the Covenant, 67 Newbury St., Boston. Al Pacino of The Godfather sets the murderous Machiavel to school in an interesting though imperfect production.

Wating for Godot. Caravan Theater. 1555 Mass. Ave. A few sex changes, but otherwise Beckett's.
