The point of having McColl in among the major figures in Irish Traditional Music is the major impact he had on the way it's developed over the past genration.

As derry says, noone will be thinking he's Irish as such (though a surprising number assume he was Scottish.)I suppose his picture could have been put in the "other images" part of the site. Along with the picture of a pair of copulating rhinoceroses - and I don't think they are Irish either. But in with the traditional musicians seems a more sensible place for him.
