Question: Gunmen from Laredo starred which narrator of "Frontier"?

full_context: Document 1: The Tycoon (TV series): The Tycoon is a 32-episode American sitcom television series broadcast by ABC. It starred Walter Brennan as the fictitious businessman Walter Andrews, similar to his birth name of Walter Andrew Brennan. As chairman of the board of the Thunder Corporation that he founded but no longer actively runs, Brennan plays an eccentric and cantankerous millionaire (when such persons were much fewer in number) with a common touch who helps promising persons in need. The series aired with new episodes at 9 p.m. Eastern time Tuesday from September 15, 1964, until April 27, 1965. It continued in reruns until September 7, 1965. The program did not develop sufficient audience, presumably because viewers may have preferred the versatile Brennan as the bucolic Grandpa Amos McCoy in his 1957-1963 ABC and CBS sitcom "The Real McCoys". Oddly, "The Tycoon" has the same name as an episode of "The Real McCoys" also called "The Tycoon," which aired four years earlier on August 23, 1960.

Document 15: No Name on the Bullet: No Name on the Bullet is a 1959 American CinemaScope Eastmancolor Western film directed by Jack Arnold starring Audie Murphy, Charles Drake and Joan Evans.

Although it is one of Universal Pictures modestly budgeted vehicles for World War II hero Audie Murphy, the top-billed actor is unusually, but very effectively, cast as the villain, a cold-blooded gun-for-hire.
