The Wizard of Oz in Concert: Dreams Come True, on TBS & TNT ...& VH1?
IMDb; Oz Wiki; Wikipedia

Um... when I first started this page, Wikipedia said this aired on TNT. Sometime later, it said TBS. Now it says it aired on both networks. But I'm pretty sure I watched it on VH1, and I don't recall it being a rerun. I suppose it could have been, but I think it just as well could have aired there at the same time as or even prior to it airing on those other networks. (Or maybe I'm completely mistaken about where I saw it.) I don't know. And I suppose it doesn't matter.

Anyway, I don't remember it well, all I know is I liked the cast. Dorothy was played by Jewel. I was a big fan of hers at the time (1995). But the rest of the cast was really cool, too. Dunno what else to say, though. I'd probably like to see it again, someday.
