What *is* that opening theme?
So far I've heard the same song on:
FGCtU
Das Boot (When the propaganda announcement comes on over the loudspeaker, with this music as an opener, before the Chief screams "turn it off.")
And, today, again whilst listening to an old Lone Ranger OTR program. It seems to have been used as an alternative to The William Tell Overture for theme music.
So: what is that opening music? I feel as though I should know it, (Wagner, perhaps?) but I don't.
Can anyone help?
