A few versus that connect you........what song is it?

Sometimes it's like someone took a knife, baby, edgy and dull
and cut a six-inch valley through the middle of my skull
At night I wake up with the sheets soaking wet
and a freight train running though the middle of my head
and only you, can cool my desire
Oh, oh, oh, I'm on fire

Out on the road today
I saw a Deadhead sticker on a Cadillac
A little voice inside my head said:
"Don't look back, you can never look back."
