Wow look how open they're playing "C"! The PM was one of THOSE guys like "I want to see those fingers come all the way off!"

And no "open C" in that band!

Hmmmmm, I don't think so Richard. The two pipers on the flanks are clearly playing D while the piper in the centre is playing C or else about to execute a D throw which which would be consistent with the other two who are already on D. An open C is the top finger on your right hand or the pointy finger while the birl finger would be off.
