Driving the edge of a knife

Say, go through the darkest of days
Heaven's a heartbreak away
Never let you go, never let me down
Oh, it's been a hell of a ride
Driving the edge of a knife
Never let you go, never let me down

Don't you give up...

...

Don't fall asleep
At the wheel, we've got a million miles ahead of us
Miles ahead of us
All that we need
Is a rude awakening to know we're good enough
Know we're good enough
