Walker, Texas Ranger

Walker, Texas Ranger is an American television western/police drama/Action series, created by Lesie Grief and Paul Haggis. It aired on CBS with three pilot episodes followed by nine full seasons, from April 21, 1993 to May 19, 2001, was broadcast in over 100 countries, and has since spawned at least one made-for-television movie. It was originally conceived on August 6, 1987. DVD sets of the first, second, third, fourth, fifth, sixth and final seasons have been released. At various times since 1997, reruns of the show have aired, in syndication, on the USA Network, and Showcase Action,
The show was known for its moral values. For example, the characters refrained from the use of drugs, and they participated in community service. Martial arts were shown prominently as the primary tool of law enforcement and occasionally as a tool for Walker and company to reach out to the community.
The show has gained a following for its camp appeal, thanks largely to its improbable combination of martial arts and modern Western genres, and to the resurgent popularity of its star, Chuck Norris.

And this is the letter of the song.

In the eyes of a ranger,
The unsuspected stranger
Had better know the truth of wrong from right,
Cuz the eyes of a ranger are upon you,
Any wrong you do he's gonna see,
When youre in Texas look behind you,
Cuz that's where the rangers are gonna be
