Gilda - Put The Blame On Mame Chords

This is Put the Blame on Mame from Gilda, by Alan Roberts and Doris Fisher
 
I am not a guitar grand master, but have been wanting to play this song for years
and could never find a tab on the internet. After waiting and waiting for someone
else to put one up, I finally figured out a basic version myself. So I don't claim
that this is the master tab, only that this is the simple, basic chord progression.
I hope you will build upon it and resubmit!
 
In the acoustic version in Gilda, it's played with capo on the 6th fret.
