There's a big difference between melodic bagpipes and true Scots bagpipes. You don't realize it until you're in a church and a single guy comes down the aisle playing, by himself, "Amazing Grace". It isn't melodic. It's scary and warlike.
This one isn't quite like what I know, but it starts out almost the same.
