"I can honestly say I never long to be onstage again," says Ulvaeus, 63. Instead, he loves to run his small airline and write op-ed pieces. Divorced from Fältskog in 1980, he lives on the island of Vågaskär, Sweden, with wife Lena, who has battled leukemia since 2003. "Looking back," he says, "the person there onstage is so foreign to who I really am."
An avid skier, Lyngstad, 62, lives in Zermatt, a Swiss village at the base of the Alps where British royals often cavort. A widow since 1999 when husband Heinrich died of cancer, Frida—the only member open to an ABBA reunion—dedicates her time to charity. Says a pal: "She likes a normal life. She's not one for the glamour."
Anderson, 61, broke Swedish pop-chart records when his band's 2004 hit, "Du Är Min Man" (translation: you are my man), held the top spot for 38 weeks. Worth over $125 million, the music mogul owns a hotel and horse farm. Says Andersson, who remarried after divorcing his ABBA mate Anni-Frid Lyngstad in 1981: "[ABBA] shared a wonderful thing together."
When she showed up at the Mamma Mia! movie premiere hand in hand with Lyngstad, it was only the second time in 22 years she joined her bandmates in public. The reclusive Fältskog, 58, even danced with Meryl Streep on the red carpet. Apart from a 2004 cover album, My Colouring Book, she prefers a quiet life on an island outside of Stockholm.
