NEW YORK - Reuters - How can ABBA fans resist "Mamma Mia!"?

The ABBA-inspired musical romance has earned $100 million at the worldwide box office after just two weeks of release, with the No. 2 opening in North America this past weekend kicking in $28 million.

The accompanying soundtrack debuted at a staggering No. 7 on the Billboard 200 album chart Wednesday, doing much better than any ABBA album ever did.
