I'm more than a little bit obsessed with Some Days Are Diamonds and would love to learn how to play it. There are a number of "how to play" videos on YouTube and every one of them uses a different strum pattern, none of which seem quite right.

Can anyone help? I'd like to use the same pattern as John Denver uses in this video. There is a close up of his right hand at 1:48:

PS -- A very surreal 1980s German video... only one I could find of him doing it live.
