There is only one riff throughout the song and it goes something like this: 

    E     D     A     G5     
e|--------2-------------------| 
B|--------3-----2-------------| 
G|--1-----2-----2-------------| 
D|--2-----------2-----5-------| 
A|--2-----------------5-------| 
E|--------------------3-------| 

Play this throughout whole song
