 every once in a while, change the verse riff with one of the       
 variations. a second (lead) guitar plays the fills over the riffs. 
 
*chorus "let the sun..."

 there's also a transition period between the chorus rhythm  
 and the restarting of the verse riff, that's just an E5/F#5 
 slide, and held out, nothing special.                         

enjoy.
