The theme song was taken from a recording of "Puffin' Billy", a short piece
composed by Edward White that had been used as theme music for "Murder Among the Statues" and "Children's Favourites",
BBC radio programs in Britain. A recording happened to be in the CBS library when the
Captain went looking for a theme and we heard the song from 1955 to 1974. A "Puffing Billy" is an early style steam
locomotive, and the music was written for such a locomotive seen on the Isle of Wight.
Olson Computers provided a MIDI file.
Gerry Marshall provided an MP3 of the original BBC recording.
