Well , they aren't a real band , but the "lead singer" guy is an actual human being. His name is Eric Jean Violette and he's a musician and actor from Montreal. The American versions of the ads use a dubbed voice to cover up his accent as he's a funky dude and they wanted him in the commercials. He also has a twitter under @EricViolette . He's also a 28 year old Gemini. Hope this helps.
And for your viewing pleasure , all of the freecreditreport.com ads.
