What was the song Kurt Russell singing in video at end of movie 3000 miles to graceland?

The song Kurt Russell sings at the end of "3000 Miles to Graceland" is "The Ballad of Davy Crockett".

This song was actually originally sung by Fess Parker in the popular television series "Davy Crockett" in the 1950s.

Russell's rendition in the movie is a humorous and somewhat exaggerated version, which fits the film's overall tone of over-the-top action and humor.
