ABBA celebrates 40 years of global success since 'Waterloo' breakthrough

Within strolling distance of the train station bearing the name of their first global hit, Swedish band ABBA celebrated 40 years of pop success to mark their groundbreaking song Waterloo.

Two of the four members of the band that made spangled jumpsuits and big boots a trademark attended the bash at the trendy Tate Modern museum on Monday night, marking four decades since their catchy tune won the Eurovision song contest in April 1974 and launched them into international stardom.
