Mamma Mia! An ABBA museum!

A museum dedicated to the music, clothing and history of Swedish supergroup ABBA will open in Stockholm in 2008.

The interactive museum will feature original outfits and instruments used by ABBA, handwritten song lyrics, a display of awards and "all other things we can think of and find," said Ulf Westman, an event consultant who is spearheading the project with his wife, Ewa Wigenheim-Westman.

The four band members will donate the material for the exhibits but will otherwise not be involved in the project, which will be funded by company sponsors, Westman said.
