When we're out and about on the weekends, some of us are lucky enough to be entertained by a fellow bar-goer stepping up to the mic and singing a karaoke favorite. Most of the time we politely clap to let them know we applaud their bravery, even when the performance was just okay. Then there are the times when someone grabs the mic and absolutely blows minds! 

Kevin Stephens captured an historic moment in Maine karaoke history! It happened recently at Sea Dog Brewing Company in Topsham. We don't know who the guy singing is but he's got Brian Johnson's vocals down pat Here he is giving all his throat has with AC/DC's Thunderstruck!
