You Are My Lucky Star - Debbie Reynolds own voice - Singin' in the Rain

I always thought that Debbie sang this finale, since she sang this song in an earlier deleted scene, and since she sings the version of "Singin' in the Rain" that comes right before it. But comparing her two takes with the one in the film makes it clear that Betty Noyes dubbed her for this song. Here's one of the takes of her original vocal, along with an alternate ending (no chorus).
