Fave TV Theme from the 70's?

Not so much the theme, as the entire concept of the opening credits. The Six Million Dollar Man. A viewer new to the show could watch a random episode, and the opening credits would set the premise upr.

For an actual theme. Possibly Kidnapped (1978 UK miniseries). A beautiful piece of music.
