I've played in bands both standing and sitting. As I don't ever see the dancers scrutinising the band whilst they are dancing, I can't see it really matters. Some musicians can play better standing and some better sitting. In one band I played with I was criticised by the other musicians for standing up whilst playing the accordeon as they all wanted to sit down. I never saw the Ranchers stand whilst playing but I suppose they could have used bigger dots? What do you do, Mo? Stand or sit?
