Yeah the mix for Shania was much better in the field. Sounded great there, I had a really good time.
Her vocal issues are quite well documented - she had an illness which completely destroyed her voice, had to have vocal surgery and learn to sing from scratch. She's said that it's a difficult decision about whether to mime and sound closer to the recordings or do it live but sound how she now does. I much prefer a live rough vocal than a clean mimed one, fair play to her for carrying on.
