Re: you don;t mention what key you are trying to actually play it in..
I was trying to play it in the exact key that Carrier was, but, seems I was off. After I got my piano keyboard, I realized I was misinterpreting the Transcribe spectrum view. Instead of the tallest note curve shown on there, I should have been looking at the tallest pointed curve.
When I play it, people say I'm playing in Bb. I play on the C/F rows.
The video I put up on it shows how I play it. Check link #2
When played on an F/Bb/Eb triple row, it is in the key of F, played in the 2nd position on the 2nd row. Think of that as the "home" position. But, there's a whole lot of going across the rows happening here.
I posted a video on YouTube showing how I think this song is done. See Link# 1.
This is a good, simple song that illustrates several important things about playing Zydeco on a triple row. It has the flat 3rd. It has the F may triad played on the pull, with the root note, F, grabbed from the inner row. Other things too, which I try to point out on the video.
