“Fiddler on the Roof” will offer several performances this weekend at Providence Performing Arts Center. In the little village of Anatevka, Tevye, a poor milkman, is trying to keep his family’s traditions in place. But, times are changing, and when Tevye’s daughters want to make their own matches, he must choose between his own daughters’ happiness and those beloved traditions that keep the outside world at bay. The production stars real-life husband and wife Jimmy Ferraro as Tevye and Dee Etta Rowe as Golde.
