This is not the whole song just a tiny part that I figured out. 
Use your first finger to hold down the second string on the first fret. 
Then use your second and third fingers to do the rest. 


E|-1-3----3-1----1-0----0-1--------- 
B|-----1------1------1------1------- 
G|---------------------------------- 
D|---------------------------------- 
A|---------------------------------- 
E|---------------------------------- 
That's all.
