FOUR-WHEEL DRIVE
Words and music by Bill Fries & Chip Davis
As sung by C. W. McCall on "Wolf Creek Pass" (1975).

We was screamin' through the valley where the Nishnabotna flows,
Through the mud 'n' the crud 'n' the cornfields where the mari-jee-uana grows,
Crossed the railroad tracks at Persia, down the hills and up the dale,
That CJ-5 with four-wheel drive an' Smokey on my tail.

Well, he picked me up at Exit 12 on the I-Six-Eighty ramp.
I was doin' sixty-seven per when I rumbled through his trap.
He commenced to whirl his flashin' lights an' he made his siren wail.
I slipped on down to four-wheel drive with Smokey on my tail.

Now I got racin' stripes an' dual pipes and Smokey's got a Ford.
Got a mill with a four-pot carb, ya know, but Smokey's stroked and bored.
Well, the chase was on but I had the edge with a rig that'll never fail.
Got a CJ-5 with four-wheel drive an' Smokey on my tail.

Yeah, he was...

Well, I dropped on down to granny low, an' I made a hard right turn.
My big ol' fat Commando tires went slashin' through the corn.
Well the tassels blew, an' the kernels flew, an' it looked like yellow hail,
Just cookin' alive in four-wheel drive with Smokey on my tail.

Well, we went screamin' through the valley where the Nishnabotna flows,
Through the mud 'n' the crud 'n' the cornfields where the mari-jee-uana grows.
Crossed the railroad tracks at Persia, up the hills and down the dales,
My CJ-5 with four-wheel drive an' Smokey on my tail.

Look out, now; here he comes...
Ohm we gonna get it on now...
Don't hit that fella with the banjo...
We gonna swim this here crick now, Smokey...
Yard wide an' a foot deep...
Nishnabotna River they call it...
Might have to winch out...
Don't do a wheelie on that there gopher mound now, Smokey...
Can you dig it, Smokey?...
Got four on the floor an' four in the air on that one, didn't we?...
Goodness gracious!...
Like to bust my shocks...

Well, that Jeep of mine made Smokey whine; his rig was made of lead.
He was mired in fourteen feet of mud, so he radioed ahead.
I pulled up onto the blacktop, went crashin' on through the rail.
Sakes alive! I had twenty-five more Smokeys on my tail.

Now I got racin' stripes an' dual pipes and Smokey had a Ford.
Had a mill with a four-pot carb, ya know, but Smokey's stroked and bored.
Well, the race was on but I had the edge with a rig that'll never fail.
Got a CJ-5 with four-wheel drive, settin' out back of the jail.
