I saw Mamma Mia on broadway once and though I liked, once was enough. When I saw Pierce Brossman was in the movie I did want to see it. My girl friend talked me into the sing along version. I thought that would be lame but it was not!!! I loved it and we sang along and alot of singing to each other. I even want to see it again. We are taking our kids, who also saw it on broadway. I truely loved it
