Irving = Isaiah?

Talking about Isaiah Berlin the other day, I almost said Irving Berlin. But has anyone ever seen them together?

For instance, consider the lost first draft of the lyrics to the American standard "Let Yourself Go" from Follow the Fleet. (Note: Before doing this, you may want to read the comments to this post.)

Crooked timber
Means that all things built are limber
Nichts Gerades wird gezimmer'
Let yourself go

I'm just saying, is all.
