Chorus and Intro (Intro without words):
      D5      A5              B5           G5
     I Don't wanna grow up, Don't wanna Figure this out
      D5        A5           B5               G5
     I Know you set me up, Don't want this getting you down


I'll try to get the rest up later but this is all I know of it so far.

This isn't entirely accurate but it's very close and this will help you figure it out so 
have fun with it
