Dr.,

Did you by chance make this video private?

When I click on the website link, youtube says:
"This video is Private".

Merci,

the flat 3rd -> major 3rd slide is the *single* most used trick in all of 3 row playing

you can do it on the outside row and the middle row
you find the flat 3rd in the row 'above' - more inside

on a F Bb Eb, you would be in C on the F row
the flat 3rd of C would be Eflat, of course it is in the Bb row
pull
find the E on the C row
the Eb will be one row above and about 1.5 buttons farther from the floor

yes, in either octave

Yes, it is in the key of C, played mainly on the outside row of an F-Bb-Eb triple row. As Larry says, it uses the minor third/major third blend as a very important part of the song. That's what makes it bluesy.

On your G-C-F, I suppose you would play it in D on the outside row.

I think it is the very first recorded zydeco hit. Boozoo beat Clifton to those bragging rights by a year or so.
