The dream team of ABBA. To a lot of people at least: Björn and Frida. Was there something going on between them. I don't think so, they were just collegues. Still, what a match!
Never mention anyhing that suggests partnerswapping on ABBA the Site. Even if you think it's only a harmless joke, your post will be deleted immediately!
Imagine the ABBA members might read it! OMG! Imagine they did swap partners from time to time! OMG! What if they think we know? Or what if we know that they know that we know???
