In the wind and rain of winter and no glimmer of the
sun,
We leave the south behind us on that welcome northern
run,
New motor just been fitted and she's barking from
stack,
A snarling Detroit diesel underneath this big old Mack.
There's bull lights on her bumper and new chroming on
her stack,
Her reconditioned gearbox has really brought her back,
New booster on her intake and her head is made to suit,
And when I hold her open Holy Moses can she scoot!!
She's a road train geared for the open road and the
inland highways,
Known to the rugged north and the dusty byways
Big old Mack.
Two weeks too long away from all that diesel oil and
grime,
Tonight we’ll see the sun go down across that
borderline,
There's lots of work to do old girl and we've no time
to sleep,
Your big repairs have left me broke and you've gotta
earn your keep.
[Instrumental]
We’re rollin’ up the highway all the blues are in our
wake,
The bogey wheels are humming to a good old country
tape,
Two trailers on we dare to pass the truckies gasp in
awe,
We’re sailing round their modern trucks half throttle
to the floor.
She knows that Goulburn highway and she knows old
Goulburn Hill,
And the endless blue horizons on the road to Camooweal,
She knows that sunset country where the wedge tailed
eagle soars,
And the unforgiving distance of the lonely Nullabor.
She's a road train, geared for the open road and the
inland highways,
Known to the rugged north and the dusty byways,
Big old Mack, big old Mack.
