From the recording The Sun King
Lyrics
If I have got a part to play, well then fine
So let it be revealed
If I have got a light to shine, well then shine
Don't let it be concealed
If I could only change my way today
I would, and it would be for good
Oh, black book, oh black book
Black as a rook; just an old black book
Oh, black book, Black Book of Carmarthen
You old, you black book
You have helped us to see how the mighty dead survive
If I have got a card to play, well then fine
But let it be for real
If I received a mighty sign today, then fine
But let me know the deal
If I could only change my way today, I would
And it would be for good
