Abba's four members have little incentive to do much of anything these days. Their catalog continues to pump tons of money into their bank accounts, and the musical Mamma Mia! packs theaters every night all across the world. Aside from that, the group consists of two divorced couples. So it's no wonder they've reportedly turned down offers of a billion dollars for a reunion tour. Of the four, Agnetha Fältskog keeps the lowest profile, reportedly rarely leaving Stockholm. She showed up at the premiere of the Mamma Mia! movie in 2008 – but only posed for photos on a balcony with the movie's cast, far away from her three former bandmates. And she was nowhere to be seen when Abba got inducted into the Rock and Roll Hall of Fame in 2010.
Barrett Scale: 6. Fältskog isn't seen very often, but she did release a solo LP in 2004. Still, skipping out on the Hall of Fame induction scores her some big points, as does her apparent reluctance to venture outside of Europe.
