Seventies supergroup Abba are to be honoured in their native Sweden next year (13) with a special museum exhibit in Stockholm.

The collection will feature the quartet's glitzy stage costumes, instruments, and other personal mementos.

Abba The Museum will open its doors in the spring of 2013 as a sub-section of the Swedish Music Hall of Fame on the island of Djurgarden, but fans should not dream of a reunion at the launch.

Bjoern Ulvaeus tells the Associated Press, "We are the only group of that status that has never been reunited. I think that is cool. It is a strength for Abba that you remember those young, ambitious, energetic people during the '70s rather than some feeble old folks who feel compelled to get up and play all the time.

"We quit at the absolute top. And when we stopped it was to take a break and do some other things and then get back together again. But it never turned out that way."
