Bachelor Father Deck The Halls

Deck the Halls is one of those BF episodes that's never shown--and there are quite a few others. My theory is that a lot of the music rights have expired, so they were pulled.

I think, as the years rolled on, Forsythe was quite willing to spend $ on music rights, where most other sitcoms used public domain material.
