Well, gentlemen, you have had your say, but I am going to buck the trend and say that I love both those tunes.
I have Scotland the Brave as my mobile phone ringtone, as it brings to mind the times I marched in a kilt with my regiment and the St Andrew’s College band in Grahamstown.
And if you have seen the movie Amazing Grace, you will grasp a little of what the words are about.

Canuck of NI wrote: “I remember that they were written by a former slave trader from the 19th Century, who had some sort of Road To Damascas experience and became an anti-slavery activist?”
Actually the 18th century. His name was John Newton, and that road to Damascus experience was the beginning of a saintly career that produced dozens of hymns, many of which are still sung regularly in those churches that have not gone over totally to guitar worship.

Granted, Amazing Grace has been overplayed in various forms – on the pipes, on brass instruments, and sung by people who don’t necessarily have the voice to carry it.
But it remains a tremendous testimony to a life turned around by the grace of God.
There are cheesy renditions of it, but it definitely not a cheesy tune.
By all means let’s have other tunes on the pipes as well. But don’t decry this one just because some folk have done it badly, or too often.
Regards,
Mike
