Lyrics:
"Get your motor runnin'
Head out on the highway
Lookin' for adventure
And whatever comes our way
Yeah Darlin' go make it happen
Take the world in a love embrace
Fire all of your guns at once
And explode into space

I like smoke and lightning
_____ _____ thunder
Racin' with the wind
And the feelin' that I'm under
Yeah Darlin' go make it happen
Take the world in a love embrace
Fire all of your guns at once
And explode into space

Like a true nature's child
We were born, born to be wild
We can climb so high
I never wanna die

Born to be wild
Born to be wild"
