Partygoers flaunting crimped hair, leg warmers and sport coats filled Tuttle’s bar in Hopkins for the Get Your Rear in Gear Booty Ball to benefit the Minnesota-based Colon Cancer Coalition. Guests enjoyed a 1980s costume contest, silent auction and a taco bar while a synth pop ’n’ roll band, Brat Pack Radio, played ’80s hits all night. Gnarly!
