The clip below comes from the 1942 Charles Starrett B-Western "Pardon My Gun," and features the cowboy singing group Texas Jim Lewis and His Lone Star Cowboys. It's shot on the Iverson Movie Ranch, among a group of buildings called the Middle Iverson Ranch Set, also known as Halfway House. The song is "Sing Song Kitty." It's not in sync, but it makes up for it by being short!
The clip features a couple of the buildings that made up the ranch set — especially the main house. The early barn can also be seen in the background. Click here for more photos of the place in a detailed blog post focused on the Middle Iverson Ranch Set.
