Gene Roddenberry wrote some of the first episodes.
I read that Richard Boone helped write the title song.
Yes he did, I mostly try and pay attention to the credits in those old shows.Paladin, gunsmoke,rawhide were all done by CBS, lot of the same writers , actors and directors in the mid to late 50’s.
One old gunsmoke episode had a very young Arron Spelling as a featured guest star, “the guitar” I believe it was.
