About the theme music making good guitar music, Guy Van Duser beat ya to it. I have an LP from about 1977 with "Great Western TV Medley" which was a staple on the great KFAT radio in Gilroy, California. It seems to be part of a newer CD with 19 cuts, Rounder, about 1988.

As far as Ward Bond's acting, John Ford tried to have a small part for him in most of Ford's movies. John Ford considered him one of our greatest actors, and his opinion carries some weight.
