CAJUN ACCORDION DISCUSSION GROUP
I thought I was hearing some Allman Bros motifs in there!
I still think it is on the pull, not the push. On the triple row, you could play it on the outer row (the F row) on the pull (key of C). This is assuming an F/Bb/Eb triple row.
But, you kinda already said most of that. Don't mind me - I work in the Dept. of Redundancy Dept.
