I was baffled by the question too. There's a lovely harp arrangement of it by the fine Scottish harpist and teacher Jean Campbell, which my students all like. I wonder if the fact that it's an instrumental version exempts it from the charge of lacking a "point" since it also lacks words?

But - the power of Mudcat - even an apparently pointless *thread* can generate interesting and worthwhile responses. Still no wiser as to what the problem is though...
