Walking into the Winter Garden Theatre this week to see the new revival of "Mamma Mia!," I suddenly found myself back on Oct. 18, 2001. I was there at the Winter Garden then not as a critic but a theater reporter who had already written a lot about 9/11 and its devastating effect on the theater in New York City.

If you love Mamma Mia !, you’re gonna love Mamma Mia! With the touring production of the hit ABBA musical making a six-month stop on Broadway, the flawed, fun-loving show returns to the venue – the Winter Garden Theatre – where it held sway back when the century was new.
