A museum dedicated to pop supergroup Abba is to open in Stockholm, Sweden. The three-floor attraction will feature a wardrobe room, where the foursome's glamorous costumes will be displayed, and an area where fans can make their own recordings of Abba songs. Abba - Benny Andersson, Anni-Frid Lyngstad, Agnetha Faltskog and Bjorn Ulvaeus - are donating memorabilia including clothing and instruments to the museum, to which they have given their blessing. The centre is being built at a cost of 200 million krona ($30.6 million/GBP15.3 million) and is due to open in 2009.
