Ref Kendall's message,I think the Slim Dusty song was called "Lights on the hill" written by his wife Joy McKean.

Slim sang loads of Australian trucking songs, and occasionally recorded whole albums of the genre, e.g. "TRUCKS ON THE TRACK" and "LIGHTS ON THE HILL". Other notable songs are:-

"The worst in the world"
"Foggy mirrors"
"Bent Axle Bob"
"There lies an old workhorse"
"Kelly's offsider"
"I don't sleep at night"
"One truckie's epitaph"

and loads more.
