I like it! Used to play Ghost riders on harmonica in a skiffle band and always remember the tune for its atmosphere, a really good context for mardi gras song. You've inspired me on this one.
So.. Peer.. The video says that it's in Am on a C accordion. What makes it Am?? This is from a guy who has to count the buttons to find a G or D note. No music background.
I do know that the C accordion is all major notes.
