Broadway On The Plaza: 'Mamma Mia!'

(CBS)  The Early Show's Broadway on the Plaza continues with the cast of "Mamma Mia!," the hit musical that has broken virtually every known British box office record in history and is now taking North America by storm.

"Mamma Mia!" is based on 22 songs from the '70s Swedish disco group ABBA. The musical somehow pulls off putting together all the songs to make a linear story. The story takes place on a Greek island, where 20-year-old Sophie is due to be married.

Sophie is loved by her mother, Donna, but she is unsure who her father is. So, she looks into her mom's diary, chooses three former lovers as likely candidates, and invites them to the wedding, thinking she will figure it out when she sees them. Donna's reaction to seeing her old flames is interesting, to say the least.

The musical opened Oct. 18, 2001 on Broadway, a few months after the Sept. 11 attack on New York City. Louise Pitre, one of the principal cast members, says she believe "Mamma Mia!" was able to put a smile on Americans during a serious and heart-wrenching time.

Pitre made her Broadway debut in "Mamma Mia!" last year and received a Tony nomination for her work. She has released a new CD of her own, called, "All Of My Life Has Led To This." The album features two songs from the musical: "The Winner Takes It All," and "Flipping Through My Fingers."

The cast of "Mamma Mia!" performed on the Plaza the recognizable, toe-tapping tunes "Dancing Queen," "Mamma Mia!" and "Money, Money, Money."
