"we know nowt about folk music compared to pre pubertal Scots people."

I don't believe that anyone is saying or suggesting that but many of them are certainly more talented and knowledgeable than I was at that "pre pubertal age" and in many other areas too besides folk music.

Of course, such youngsters have had more opportunities than me(and most of us here, I'm sure).   On the other hand, many other young people still don't get these and are, sadly, even worse off than we were in many ways.
