Kim C, don't get me wrong. I love Yul Brynner --even though he played himself in everything he did (like John Wayne).Jerry and Wesley, don't forget that Buddy Ebsen started his career as a vaudevillian song-and-dance man. I don't think he'd have been at all bad as the scarecrow.
(Peg, I think you meant to say Ebsen was replaced by Ray Bolger. Bert Lahr played the cowardly lion.)
