Mamma Mia! The Swedish pop group ABBA is the subject of a theme park that opens Tuesday in London — ABBAWORLD.
ABBA has sold 400 million records since its 1970s heyday and spawned the hugely successful stage and film musical "Mamma Mia."
Swedish organizers say the theme park will be "a place for total interaction" with the band.
The exhibition tells ABBA's story in 25 rooms, displaying costumes, a recreation of the band's Polar Studios and even the helicopter on the cover of the 1976 album "Arrival."
The four former members of ABBA support the project and have donated memorabilia as well as recording interviews for the exhibition.
