I was going to say the same as Allan Conn about the Scottish Traditional Music version of the Hall of Fame, which sounds somewhat different from the American version. I cannot think of anyone on the Scottish list who is/was not entirely deserving of that recognition, and as the list of categories shown in Allan's link, this can be for a wide range of varying services to Scottish music, all of which are an integral part of it. And some have been made posthumously. I have heard of a couple of people who should be up there, but have turned down the award, but they are nonetheless revered for their contributions to our music.
