Never Make Me Cry key signature

[aleuzzi]

So, I have the same FM music book a lot of you have with basic arrangements for songs from the white album, Rumours, and Tusk. I’ve played through a lot of the Tusk tunes on my piano. In that book, “Never Make Me Cry” is transcribed in C major. I never questioned it—the art of Christine simplicity and all that. But today I played along to the recording and found she’s singing in C sharp (or is it D flat?). This strikes me as highly unusual for her. By her own admission, she preferred her “root notes” to be on ivory keys because her hands slipped off the ebony ones. The only other song of hers I can think of with a root note on an ebony key is “Warm Ways.”

Anyone have a take on this and/or more knowledge about NMMC’s key (David?).
