Mama Mia, here they go again - yes, Abba are back in town. A new museum-come-theme park with music, mementos and glitzy costumes worn by the Swedish glam group can now be seen by pop fans in London.

Is it possible to have too much Abba? Knowing me, knowing you, the answer is probably no.

The Swedish supergroup that gave the world "Waterloo" and "Dancing Queen" has sold 400 million records since its 1970s heyday and spawned the hugely successful singalong stage and film musical "Mamma Mia."

Now, pop fans, welcome to Abbaworld.

Abbaworld's Swedish organizers promise the exhibition will be "a place for total interaction" with the band.

Abba's music is inescapable throughout the park, from the exuberance of "Dancing Queen" through to the melancholy of "Knowing Me, Knowing You" and "The Winner Takes It All" - reminders the band started its career composed of two married couples and ended it two divorced ones.

The exhibition tells the band's story in 25 rooms spread over 30-thousand square feet.

All four band members support this event, and have donated memorabilia, as well as recording interviews that are played on screens in the exhibition.

Organizers hope to send the show on tour after its London run - currently scheduled through March - and to open new versions of the exhibition in Australia and New York by the end of the year.
