Troublesome Trucks

Thomas and Friends was produced in the UK, but was introduced to the US a few years later with a redub to better suit the American audience. The following is a scene from Season 1's "Troublesome Trucks" ("Foolish Freight Cars" in the US), showing the original UK narration by Ringo Starr, the US narration also by Starr that changes specific lines (ie. "trucks" to "freight cars"), and the redubbed US narration by George Carlin on later releases.
