Just came across these amazing clips on YouTube! Have never seen any of them and they are remarkable! The on-set clips from Solomon and Sheba alone are incredible!!

I think I know the 'Solomon and Sheba' clip on You Tube you refer to. Is it the 20 second piece narrated in Spanish? If so, he looks terrific there, so much better than many of the candids from that period! Wish it was longer. I'll look for those others.
