Kad said: "Why would they remove the Minstrel? They’re a rather key role and they’re of course also part of the song “The Minstrel, the Jester, and I.”"
In the latest of the three TV versions, wasn't The Minstrel cut? It's been a long while since I've seen it; my memory is a bit hazy. I think in the '72 version, the Wizard was axed in favor of a slightly different character.
With so many versions out there, it's hard to say what might end up on stage.
