Few weeks ago we had a cajun accordion workshop dans les Pays Bas...
In the link above you'll see our accordion teacher Bs van der Poll playing the twin fiddle, Wilfred on (borrowed) Acadian accordion and me on guitar. (the other band members: Cristel on lead fiddle, Mirjam on 'tit fer (she also plays accordion in daily life) and Wytze Pieter on dubble bass.
There's also better quality audio recordings available with Bas singing while fiddling. So if you want to hear them, send me an email ( replacing 'at' with @, of course)
