Poorboy Shuffle (Creedence Clearwater Revival)

I´m not really sure bout this song, but i think it goes like this:

3 -3 4 -4 3 -3 4 -4 3 -3 4 -4 3 -3 4 -4 777 -6 5 5
3 -3 4 -4 3 -3 4 -4 77 -6 55
3 -3 4 -4 3 -3 4 -4 5 5 -6 5
4 -4 5 -5 4 -4 5 -5 5 5 -6 5
4 -4 5 -5 5 5 -6 -6 6
555555556
777 -6 5 5

A couple o´notes typed together means that you hold the note for a
while.
