Description given on Youtube:
Jack O’Hagan’s composition "The Road To Gundagai" was a good choice as the theme music for the George Edwards radio show "Dad and Dave" although there is no evidence that Snake Gully is anywhere near Gundagai. The producers commissioned five versions of the tune but, unless there an episode with tragedy in it, the two slow, mournful cuts were never used. Here are the three that were. Track 1 introduced the serial, track 2 played into the opening dialogue and track 3, called agitato, was the closing music, often signifting some sort of drama or cliff-hanger situation.The serial, which still airs today, stopped production with George Edwards death in 1953. Samples of the program can be found elsewhere on YouTube.
