Q What's up with ABBA these days?
—Norman Grote, Crossville, Tenn.
The wildly successful Scandinavian pop quartet disbanded in 1982, trailing a string of infectious pop hits that included "Waterloo," "S.O.S.," "Mamma Mia," "Fernando" and "Dancing Queen." The act took its name from the first letters of its member's names: Agnetha, Björn, Benny and Anni-Frid. Their legacy includes a musical based on their music, Mamma Mia!, which last year became one of the 25 longest-running Broadway productions of all time, and an interactive ABBA museum set to open in 2008 in Stockholm, Sweden, to display some of their costumes, instruments and other memorabilia.
