I’m not a lawyer, nor do I play one on TV, but maybe someone can clue me in….

Why is it, when a public-domain series is shown on TV, almost without fail, the actual theme is replaced by some generic instrumental music similar to it….

….but incidental/background music in the episodes are okay to run?

I seem to remember watching Beverly Hillbillies on Classic Reruns TV, and the episode ended with a variation on “The Ballad of Jed Clampett” (the actual theme), but when it came time for closing credits, the public-domain music plays.

Why does the music playing during the “body” of the episode get a pass while the actual theme doesn’t?

I don’t think it could be because dialog is covering it. I’m sure that parts of “Bonanza” have situational music without any dialog.

Anybody?

Most of the music is copyrighted once and only once. So if you copyright the Ballad of Jed Clampett, it's copyrighted no matter what it gets used in - every episode, movies, whatever.

The script changes episode to episode, so it has to be copyrighted episode by episode. Thus, it can also pass out of copyright episode by episode. So, the text of an episode can pass into public domain while the underlying music remains protected under copyright.

It's my understanding it depends on the original license agreement. You can buy a lifetime license but to save money TV series usually buy a short term license which only covers the original run and a limited number of rerun years. Maybe they haven't been able to come to a new agreement to extend the license and/ or in some cases, the creators of the music have unfortunately passed on and there is question on who holds the current rights.
