Sounded like a personal preference "reason" to me as well..... However, I was not in a position to argue with the inlaw's pastor at such a difficult time. In reality, the "outside" playing had an even more ethereal effect than they would have had in the cathedral.......

My experience in the local Episcopal Diocese where I live has also not been the same. One local church even has a Kirkin O'the Tartan service complete with Highland Cathedral played by The Citadel Pipe Band.
