Over in another group, I have become involved in a discussion about the lyrics to the song "Convoy" by CW McCall
"It was the dark of the moon on the sixth of June In a Kenworth, hauling logs. Cabover Pete with a reefer on And a Jimmy, hauling hogs."
We know that Kenworth is a make of truck.
A "Cabover Pete" is a Peterbilt truck with the cab over the engine, while a "reefer" is a refridgeration unit.
However, there has been some disagreement about a "Jimmy". One poster claims it is a Mack truck, taken from the song "Jimmy Mack". Another claims that a Jimmy is a truck built by GM.
Which is correct?
