Bob Smith, the show's host, was dubbed "Buffalo Bob" early in the show's run (a reference both to the historical American frontier character Buffalo Bill and Smith's hometown of Buffalo, N.Y.). At first the set was supposed to be a circus tent, but soon was changed to a western town. Smith wore cowboy garb, as did the puppet. The name of the puppet "star" was derived from the American expression "howdy doody"/"howdy do," a commonplace corruption of the phrase "How do you do?" used in the western United States. (The straightforward use of that expression was also in the theme song's lyrics.) Smith, who had gotten his start as a singing radio personality in Buffalo, frequently used music in the program. Cast members Lew Anderson and Robert "Nick" Nicholson both were experienced jazz musicians.
