I can't imagine seeing a pantomime version of it... without speaking as well I presume? That seems rather odd, lol. But I take your word for it, it must have been good!
it had words and singing, (not a traditional pantomime, i know) but the really cool thing about it is that we got to join in! when dorothy or any other character asked a question, the audiance would yell the answer! eg: "Oh, wwheres todo?" "BEIND YOU!!" childish, but amusing
