Mamma Mia was the first Broadway musical I ever saw. A friend dragged me to see it...and afterwards I was glad they did. The energy in the show is captivating and before you know it you're singing along with the chorus. Mamma Mia is an Abba soundtrack, so their hit songs like "Dancing Queen" are prominent through the show. The closing song was "Dancing Queen" and everyone in the theater was standing and singing along with the song. Mamma Mia is a really engaging show and definitely worth seeing if you are looking for a high energy Broadway Show.
