Yow! Brings back memories of my bar band days, howling my balls off trying to sing that one just like John Fogerty...
As I recall, the intro riff is just arpegggios based on this fingering for an E7 chord: x7675x
The chords are basically just E7, with your occasional D -> A change thrown in. Lyrics, as best as I can remember 'em 25 years later:
When I was just a little boy A-standin' to my daddy's knee My papa said, "son, don't let the man getcha And do what he done to me"
