Moby - Natural Blues Chords & Tabs

This whole song is very simple, as long as you have the voice for it.
The chords I saw in another tab weren't sufficient, and I figured it out for 
myself and love playing it...so here y'go.

Progression:
[ Tab from: https://www.guitartabs.cc/tabs/m/moby/natural_blues_crd_ver_2.html ]
Am7    
Ooo lordy now, trouble so hard

F

Ooo lordy now, trouble so hard

Dm 

Don't nobody know my trouble but God,

G

Don't nobody know my trouble but God.


These chords work for the whole song...I like giving it an almost reggae strum. Enjoy.
