Two tenors and one castrato.

Admitting you like Josh Groban isn't considered cool, but these three bros couldn't care less what anyone else thinks about their musical taste. When the chorus to "You Raise Me Up" kicks in, these guys sing their hearts out. Of course, whenever there's a sing-a-long in the car, it's always the one guy who doesn't know the words who insists on singing the loudest. In this group, it's the French Bulldog. But what he lacks in pitch and timing, he more than makes up for with passion.
