"Good Night" demo?

[ahawk66]

I was just listening to the White Album, and as it closed with "Good Night", wondered if there exists a demo of John singing that one? Does anyone know? I've always heard that John wrote that one and was embarrassed to sing it because of its childlike vibe, so he gave it to Ringo. If that's the case, then maybe there's a demo of John singing it... although, if there had been one, I'm sure they'd have thrown it on the anthologies. Just curious...
