The western set seen in the show was the same set used for Gunsmoke which was also in production at the time at CBS Studio Center. The two 'On Draught' signs can be seen on both sides outside the saloon, though they have replaced the 'Long Branch' sign used for Gunsmoke with another.
The Steve Hunter character is played by Aron Kincaid. In the scene where Hunter (whose character in the episode is an actor) comes riding in on the set, the other character refers to him as "Kincaid" - a nod to his real name.
