I know the Donna thing was a joke but from all the justified criticism one can utter about her singing, being out of tune definitely isn't among them.
Just listen to any Sing Me Back Home or early Row Jimmy if you need any proof that she is incredible at vocal harmonies, hell even her GSET and Scarlet Begonias wails are pitched to harmonise what the band is playing, but that shouldn't come as a surprise from someone that has been a session vocalist for so long that she started working with big names at age 15.
Great version btw, but that is also to be expected coming out of that behemoth Bird Song
