Had to post a simpler tab to play along with Glee's version of Defying Gravity,
some of the other tabs out there are misleading.  I'll make it as simple as pie.  
I like to add9 to the G's but either way's fine.  The only chord I'm unsure of is 
the Am before the 2nd chorus but it sounds really good.
