In Need Grand Funk Railroad: How to play the introductory lick

If you guitarists have improvements please upload your own video version or offer tabs or something. I think I am close but as I say this is a hard lick to figure out because Farner seems to play several versions. Hard to discern the notes on the red album version, and on the double live set he screws it up the first time and then plays a couple clear licks. Those licks are what I used to figure out what I have presented here.
