In addition to clips of cats doing crazy things and poorly edited clips of Family Guy gags, YouTube has brought us a glut of videos of amateur rock bands cranking out video game soundtrack greatest hits.  Most of these bands jam to the overworld themes of Super Mario Bros. and The Legend of Zelda while a guy in a game-related costumes performs wacky antics and jazz-hands in time with the music and then call it a day, but one band I found during my web travels go beyond the usual repertoire.  Yes, they do Super Mario Bros., but they also perform medleys from classic games such as Sonic the Hedgehog, Chrono Trigger, Mario Kart 64, Toejam & Earl, Donkey Kong Country 2: Diddy's Kong Quest, and more.  From Brazil, it's Gameboys!
