Ah, but which "original tongue", Ron, the original original poem or the original libretto, and which TV stations abroad? The U.S. ones might just prefer it sung in American 'English'.
Sorry to say, but the likelihood of getting a Proms performance on TV in the USA, even years after the fact, is absolutely nil, even if it were somehow translated into American.
With the exception of 2-3 Live from Lincoln Center broadcasts (generally a NY Phil or Mostly Mozart concert and a Met opera or two), plus the annual Vienna Phil New Years concert, we really don't get any classical music on TV here anymore, unless Andre Rieu counts.
(He doesn't.)
