Where did these guys come from?!

Most of the greatest bands of rock and roll history appeared out of thin air. My favorite of these great bands, and arguably the best of all time, is the Beatles. They were four young school boys from Liverpool. Three were average teenagers when they formed the band. In just ten short years they changed the way music sounded forever.
