The one by Clarence Williams and band sounds (to me) more like this from a listen last evening:

Key: G

(G) I can tell by your (C) hair
You got (G) monkey in you some(C)where
And you (G) bound to look like a (D7) monkey when you get (G) old.
When you get (C) old, when you get (G)old (run it from G to E7 over "old")
You (A7) bound to look like a (D7) monkey when you get (G) old.
