Dio: Dream Evil
4. All The Fools Sailed Away
There's perfect harmony
In the rising and the falling of the sea
And as we sail along
I never fail to be astounded by
The things we'll do for promises
And a song
And as we drift along
I never fail to be astounded
By the things we'll do for promises
And a song
Dio: Magica
12. Magica - Reprise
Then it's on we sail
Never thinking that the wind could ever fail
No one gets to heaven till they've lived a while in hell
And even then it's rare
That you'll be going there
