Cause I told 'em about that little boy of mine

And how his first word about that old truck was Giddyup Go

Well today I was barrelin' down old 66 

When up beside me pulled down a brand new diesel rig

Both stacks of blowin' black coal

And as she pulled around and back in front of me

A big ole lump came in my throat

And my eyes watered like I had a bad old cough

A little sign on the back of the truck that read Giddyup Go

Well I pushed old Giddyup Go stayed right on him

Until the next truck stop where he'd pulled up

I waited till he went in and I offered to buy him a cup

Well we got to talkin' shop and I said

Now did you come by the name on your truck Giddyup Go

Well he said I got it from my pop

Dad used to drive a truck that's what mom talked about a lot

You see I lost mom when I was just past sixteen

And I lost all track of pop cause mom said he got the name from me

I shook his hand and told him that I had something I wanted him to see

I took him out to the old truck

And brushed off some of the dirt so the name would show

And his eyes got big and bright as he read Giddyup Go

Oh we had a lot of things to talk about and buddy I felt like a king

And now we've just pulled back on the old 66

And he's handled that big rig

Better than any gearjammer that I'd ever seen

Well sir now the lines on the highway have got much brighter glow

As we go roarin' down the road

And me starin' at a little sign that reads Giddyup Go
