As far as the theme song to Texas Wheelers, 'Paradise' by John Prine was the original theme song on the first few episodes. However objections by the Peabody Coal Company led to 'Illegal Smile' (also by Prine) being adopted. The line from 'Paradise', "Mr. Peabody's coal train done hauled it away" didn't amuse the folks at Peabody seeing as how it was airing on network TV. Apparently everyone thought the reference to the Peabody Coal Company was fictitious, but Peabody was indeed real, still around at the time, and definitely not amused.
