Long Islanders, prepare to meet your "Waterloo."

The music of ABBA, Sweden's biggest import since the Volvo, takes center stage at the Paramount in Huntington with ABBA Mania, a show featuring four look-alikes performing the group's hits while dressed in disco costumes fit for a dancing queen or king. Tickets for Wednesday's 8 p.m. show are $29.50-$65.

The timing couldn't be better. Not only does 2014 mark 40 years since the foursome conquered America with its hit, "Waterloo," but March is shaping up as a big month for ABBA fans.

On March 6, "Mamma Mia!" overtook "Rent" to become the ninth-longest-running show in Broadway history. Then last week, Swedish publisher Max Ström released "ABBA: The Official Photo Book," to mark 40 years since ABBA's Eurovision Song Contest win. The book, in the format of an LP, contains more than 600 pictures and back stories. Singer Björn Ulvaeus reveals that ABBA's glittery garb came about because Swedish tax laws allowed band outfits to be deductible if they weren't worn as street clothes.

"We looked like nuts in those years," he says. "Nobody can have been as badly dressed onstage as we were."
