Agnetha was so incredibly popular in her days that she had a very long fan fanatics, stalkers etc. She was every other guy's dream girl in other words. Even today, at age 65, she has 3 bodyguards that guard her when she attends in any show, for example, the premier of Mamma Mia in Sweden in 2008. They had fans at that premier from all over the world and Agentha was still afraid of the crowd and left through the back door right after the show.
Did you know Mamma Mia is the most successful musical film in his history of cinema and sits in top 100 of all time box office hits? I didn't like it at all as it was cheap karaoke from Hollywood. None of them could sing or even act properly except for Maryl Streep. The stage version of this show is much better. I've seen the Toronto version on in 2003 and loved it. In fact, it was released in Toronto first in 1999. How cool is that?
