Howlin Wolf - Moanin' At Midnight Tabs

"Moanin' at Midnight" by Howlin Wolf

This is kind of a tough one to tab. If it is not correct, I think 
It is at least pretty close.

Slight variation

The beauty of this song is the minimalism of it. This one riff just gets
played over and over and over. Listen to the song for the variation.
Please rate and comment.
