Okay so I'm not sure on the chords yet as he seems to be shifting the root note 
often and I'm not entirely sure what the tuning is on this song. 

Could be standard in which case the four chords are Am/C F G and C 
or could be drop C in which case the chords are C/A F G and C

Either way the song follows a simple pattern that is consistent throughout but 
slightly different to all the variations up here. for this Tab I'll put the chords 
up following the Root note being played based on a Drop C tuning but it's really 
just a guide and I would call the chords 1 4 5 and 6 really.
