Here is a player named Graham Irvine performing Argyll pipe tunes on button accordion. It looks to me like the box he’s playing is a three-row chromatic button accordion. I don’t listen to a lot of Scottish music but I’m not sure why, as I like this material a lot.

Untreated, folk music is apt to catch on. Witness the great folk music scare of the 60s. That could have been trouble.
The first record I ever had was a “country & western” 78 by Ernest Tubbs called Walking the Floor over You. My interest in accordion didn’t start until the 80s when I heard guys like Fernest Arceneaux and Terence Simian from Louisiana. These guys were coming up here with their Zydeco bands at the time and I ate that stuff up.
Lovely! He makes it look so easy.
This takes me right back. This is the very sound that woke me up to music – I grew up listening to my father’s Jimmy Shand records, I guess that was where the folk rot set in. My father used to call barn dances with a stereo system and a a big stack of LPs.
