If people have lived more than one life they can have soul connections to a great many cultures they were not born into in this life. If so, they will feel strongly drawn to various cultures they were not born into in this life, they'll feel a kinship with those cultures, and that may lead to them taking great interest in music or something else from a culture not presently their own by birth.

Therefore, all this nagging about which group someone was born into...as if that was the only determinant of what they should think and feel....seems silly to me.

I take it that the possibility of people having lived other lives than this present one has never occurred to most of the people arguing here? Or that you would just dismiss such an idea out of hand? If so, your dismissal of it is a strictly faith-based conclusion that carries no real weight at all since it's not based on anything real, but merely indicates allegiance to a very conventional form of thought which you acquired from others and have never even thought to question.

MacColl may have been drawn to Scots culture out of any number of different motivations...and one of them might be his own subconscious soul memory of having been a Scot, not in this life, but in another. And if so, there's no way on earth that any of you can prove it, disprove it, confirm it or deny it, because you simply don't know.

Admitting you don't know is the first step to becoming a reasonable human being as opposed to being a typical walking example of a conventional faith-based mental rigidity...which is what I find most people, in fact, are. They already have their minds all made up about almost everything. They are not about to admit they don't know.
