I think Uilleann pipers should play standing up.
In fact, I've always wanted to see an Uilleann pipe Marching Band, hobbling down the street like 20 Quasimodos, with their Bodhran section leading the way, and the Bodhran-Major prancing proudly in front like Robert Preston in the Music Man, throwing his tipper high in the air, pirouetting beneath it, and catching it skilfully (if Bodhran players can do anything skilfully) before it hits the ground.
C'mon InObu, what about it?
