Joy

	  		Here's the tab to the guitar part at the beginning, although I can imagine you figured it out yourself, it's not that difficult. 

E------------------------------------------ 
B------------------------------------------ 
G------------------------------------------ 
D------------------------------------------ 
A-4-4-----------2---2---2-4-4-4-----------2 
E-----4-5-4-5-4---4---4---------4-5-4-5-4-- 

The rest of the song has variations of that going during the verses, just try whatever fits (I couldn't hear it well enough to figure it out) 

Here's the intro chords (which are the same as the same as the Chorus) 

E (open) 

B (Bar 7th) 

F# (Bar 2nd) 

C#m (Bar 4th)
