Because Associated TeleVision (ATV) owners of ITC, also ran the London weekend and Midlands weekdays ITV companies, they tended to hold the rights for ITC series in order to show each one in the Midlands (where ABC was the weekend operator) during the week.
The series follows the adventures of Mike Malone (Paul Birch), whose nickname is 'Cannonball', and Jerry Austin (William Campbell), two truckers who haul cargo across the US and Canada for the fictitious Toronto-based C&A Transport Company Ltd.
The truck depicted is believed a GMC Model 950 COE (cab-over engine) diesel tractor built and sold in the same decade by General Motors.
The original production order appears to be lost and all that remains is a partial list based upon Canadian Broadcasting Corporation and ITV air dates.
The Cannonball TV series had a theme that opened and closed each episode composed by Joseph Hooven, Marilyn Hooven, and music packager Raoul Kraushaar.Though IMDb claims the words and music were written and performed by the American country artist Merle Haggard[4] the singer was incarcerated in San Quentin State Prison from 1957 to 1960 and would have been unavailable to work on the series.
