3. The theme song has lyrics.
At the start of the show, as with any show, there is a theme song. It’s only tunes, no words, but there are words out there. Had producers decided to use the song in all of its glory, we would have heard the words, “Bewitched, Bewitched, you’ve got me in your spell. Bewitched, Bewitched, you know your craft so well.”
