CAN'T-MISS SONG: Well, since the original versions of the tunes collected on THE ABBA GENERATION -- all classic hits of the initial Swedish hitmakers -- have already sold about 12 skidillion copies over the past two decades, it's hard to pick just one. "I really liked doing 'Super Trouper' quite a bit," says vocalist Sara Lumholdt. "And 'Mamma Mia' as well. We tried to keep the spirit of the songs, but also to add our own interpretations. We sort of had to do that, because of some of the subjects -- you can't really know the feeling of divorce or something when you're only 16."

WHERE THEY'VE BEEN: Sweden, of course -- and spending most of their time in school. "We went to dance classes together for a long time before going to audition for the band last year," says Lumholdt, who rates religion as her favorite school subject. Geography and civics get the thumbs-up from Amit Paul, who doubles on vocals and piano, while Serneholt favors history -- even though the 16-year-old is "taking a year off" from her schooling at the moment.

WHAT'S SO FABBA ABOUT ABBA?: The four teens, all of whom are from middle-class homes in Stockholm, insist there's nothing kitschy about what they're doing. While Abba wasn't exactly the top choice for boomin' systems around their schoolyards, the glitzy foursome was a constant part of the sonic landscape around them. "It's like the Beatles or something like that," says Marie. "Music your parents listen to, but not embarrassing. Also, when you start to listen more deeply, the songs are so much more complex."

MAJOR INFLUENCES: Besides Black Sabbath and Willie Nelson? "Obviously, we really like pop music, things like Mariah Carey, 'N Sync, and all that," Serneholt says. "But that's not all we listen to," adds Paul -- likely to be known as "the quiet one" when the teen mags get around to categorizing. "We all really like Bob Marley a lot, too" -- a name that elicits nods from the other three.

WILL YOU STILL NEED THEM WHEN THEY'RE 24?: "We're really happy to be doing Abba songs right now, but I don't think we'll do another record like this one," says guitarist-vocalist Dhani Lennevald -- the blond, outgoing one. "We'd like to write some of our own songs as well before too much longer." --David Sprague
