Yes, Jim's Choupique (2010) sounds more like the original Amadie 2step to me. Even when he puts a minor chord in the guitar backing. I'm sure they both have exactly the same melody line, and it's just the title that is different.
This is a version I tried to emulate like Amede's "Amede two-step". It's sort of closer to what he's doing than the choupique I made a few years ago. I don't alternate my index/pinky on octaves like Amede. That is a big part of his style. Ican't play like him, nor would I want to attempt to. But, it's closer than Choupique is.
On the new vid I do go to the note that would merit the minor chord key change (only with a guitar player, playing along, would it stand out), but with no guitar, it won't sound the same.
Since I'm playing it on an F accordion, it will be confusing to some. But, the notes I'm playing are (while in another key), closer to the melody line that Amede is playing, than with the Choupique twostep...
