Taste is everything. This is about the 4th time I've run across this show and listened to part/most of it while I was involved in something else. So I don't know jack about over-production and when I did see the TV, I'd only rank 2 of the 5 women as pretty, so that wasn't why I think it was a great show. I just thought the music was hauntingly beautiful! I also have no idea as to the authenticity of the music to being truly Celtic, but that is no matter if it is beautiful to my ears. As I say to my wife, "It was enough to please me!"
