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.
B7 is 021202
