“”Even the players were embarrassed””
Definitely some looked uncomfortable. That poor thing even started out in the wrong key. She should have stopped right there and began again - she didn’t have anyone accompanying her so it wouldn’t have been a problem. Embarrassing? Not as much as continuing did. Maybe she wasn’t embarrassed but it was certainly painful to listen to....
HOW indeed did she get so many nominations for Grammys??
Singing in a studio with unlimited takes is a lot different that singing acapella in front of a huge crowd in a stadium............
You have to work backwards from that note before you begin, or you'll wind up running out of room on top (unless you're Julie Andrews or somebody else with a five-octave range).
