I was at the Bitterroot Celtic Games & Gathering this weekend and some mates talked me into filling out the ranks by joining in with the massed bands. I am not a band member, but knew the tunes and they needed some bodies to fill out the corps. My question is: what is the proper etiquette for the national anthems and the invocation. I was at respectful attention, my pipes on my left shoulder and during both, I removed my cover. It seemed most all of the rest of the pipers and drummers did not. I realized I didn't know the proper thing to do in the situation, but I wasn't part of a band and was obviously wearing a more civilian look for my traditional Highland wear--tweed jacket and waistcoat, brown brogues and a glengarry. You Xmarkers with band experience out there: what is the right thing to do? Thanks in advance.
