Much of this is on the 1966 Invergordon Distillery Pipe Band album isn't it? I'm only a piper but I can sing the entird opening section of it along with them.
@maevealiciousawesome The open double stuff on the end is very Swiss influenced I think. I am not sure how much influence there is on the rolling part but I know the notation on my sheet music for this Duthart salute is Swiss. The open rolls/doubles on the end.... there was a name on those.... 3kamps? something along those lines.
