Presumably Sir Elton reached parts of ABROAD that the Wonderful Wizard didn't? Possibly simply because radios are more prolific than distascopes (either anbaric, or the old-timey fillum kind), and music tends not to require translation.
I also note that as a privileged westerner from the tail end of GenX, in a country with plenty of cinemas, the opportunity to see The Wizard of Oz in one has arisen precisely once, as part of an LGBT film festival[1]. If you didn't grow up with a telly full of old films, you're probably completely unaware of them.
I've probably said before, you haven't lived until you've heard Sacrifice performed with a strong Zimbabwean accent.
