Trust me, she was off (flat).
It seems a lot of people (read: Randy) can't hear when the singer is flat. He picks up on it when they go sharp, but not when the go flat.
Vonzelle tends to wander around the pitch rather than hit it. But that seems to be the tendancy for a lot of singers today. They tend to swoop up on the note because it is easier than hitting it.
I may despise her politics, but if you want to hear how to hit notes properly, listen closely to Babs.
We'll have to respectfully disagree, because I can only go by what my ears hear (and Mrs. kevkrom is even more sensitive to things being in tune and she didn't think Vonzelle was flat either).
The same caveats do apply, of course, as have for the last month -- I'm not using the stereo system and I'm short on sleep (though the baby was quiet at least this time).
