Agnetha, Bjorn, Benny and Anni-Frid, collectively known as ABBA, dominated the charts for nearly 10 years. At their height they became Sweden’s highest earners, outselling Volvo. ABBA’s timeless songs were written to be enjoyed live, and the tribute “Mania” gives audiences exactly that: two hours of uplifting, dance-inducing and sometimes heart-breaking songs like “Dancing Queen,” “Waterloo,” “Mamma Mia,” “Super Trouper,” “Fernando,” and “Take A Chance On Me.” 7: 30 p.m. Lexington Opera House, 401 W.
