Pusher Chords

The Pusher by Steppenwolf

Why are there so few songs tabbed by this great band?

Capo on the third fret. All chords with respect to the capo.

I saw a transcription of this song and it didn?t sound quite right.
So here is how it goes:

First strum an E7 chord, and hammer on the first fret on the
third string at the same time. Always use upstrokes.

The chord progression for the whole song, if I remember correctly,
is E7, Fm, G and Fm.

E7 (0201xx)
Fm (0402xx)
G  (0504xx)

Peace out and keep the Steppenwolf tabs coming ?
(this is my first tab, hope it?s not to hard to understand)
