Dio: Holy Diver
7. Invisible
Well I grew up quick and I felt the kick
Of life upon a stage
So I bought the book and took a fast look
At just the very last page
It was a single word that I'd just heard
From the two that came before
The only way to realle stay
Is to walk right out the door
Dio: The Last In Line
3. Breathless
You said a single word
But no one really heard
Sometimes we scream alone
Rainbow: Rising
2. Run With The Wolf
By the fall of the snow
A single soul will go
The footsteps on the white
There's an unholy light
