The name The Naked Brothers Band came to be because the boys played music together when they were still in diapers and "running around
naked." Still a little too risque for a target audience of children but that is where the name came from.
I think about it like a kid watching a sexual comedy like Knocked Up or Superbad, sure they won't get half the jokes but is it still ok? Once they
get used to it they will that it is ok.
