Most disco era survivors who that have enough brain cells left to remember that era would just as soon it stay dead. But for those who want to relive the days when syrupy, meaningless goo was all the rage, Bjorn Again (pictured) recreates the ’70s sound and look of ABBA. Although the monikers are a goof, this Australian tribute group, Frida Longstokin, Agnetha Falstart, Bjorn Volvo-us, Ola Drumkit, and Rutger Sonofagunn plays it straight. Be a dancing queen at the Cat’s Cradle Wednesday, Oct. 30. Call 967-9053 for tickets.
