This Guardian Angel

Shining eyes, a heavanly voice
Said: "I like your songs. I like your kind
I am your shield and I'll make you famous!"
And daydreams made the fool so blind

And then this...
This guardian angel has bought a cloud of gold
This guardian angel bags all our crop alone
This guardian angel, I guess has sold our soul

Excuse me, Sir, here's my termination
I'm famished and my purse is empty
He laughed at me: "you will go nowhere
You've signed with your blood, you'll stay forever with me!"

And then this...
This guardian angel has bought a cloud of gold
This guardian angel bags all our crop alone
This guardian angel, I guess has sold our soul
