At the Magic Kingdom in Orlando exists the ever-illusive Disney Tunnel. It's a literal tunnel under the Magic Kingdom where characters, cast members and executives can travel from one side of the park to the other without being seen.
As a Disney Cast Member, you're required to tour the tunnel during orientation. Which I did in college. It's exciting to have access to something most do not, but also quite like seeing behind the curtain in Oz; it ruins the magic a little.
I found this to be true at concerts as well. When you get to see the nitty gritty, behind-the-scenes world of Rock N Roll, it takes away some of the magic. As a fan, you know lead singers probably say the same thing at each show in cities across the world. But when it's YOUR show, you truly believe your audience is special; that the band likes you best.
Being on tour, I lost a little of the magic. But it's also amazing to see how the band DOES react to the energy of a great crowd. When the crowd is on fire, so is the band. And after seeing 60-ish Foster The People shows, it's fun to know exactly when the band is giving a little something special.
