Apparently School of Rock is real. Except without Jack Black. When I was in 4th grade I think we sang Disney songs and 'You're A Grand Ol' Flag'. My teacher definitely wasn't this cool. Granted if you listen to too much of this it could get a little annoying it's nice to see that some kids out there are being introduced to more than Justin Beiber. Apparently the teacher decided to do this when a kid in his class asked him who was in the picture in the choir room. Turns out it was John Lennon and Yoko Ono and none of the kids knew so he decided to do something aobut that.
