Thanks guys. I wasn't very satisfied with the guitar/accordion timing so I made another video. As I wear earplugs nowadays when playing, I have some trouble to hear the backing properly.
But here's one without guitar, and just a bit different. Website #3.
Up to you to decide which one sounds better.
They're both equally as swingin. Really liked the way you ended the second one. So did you make the guitar backing track? I could see it working well for a solo busking situation.
