How Can I Be Sure of You (Previously unreleased)

The other day a friend of mine said
He said, the sun's not really yellow
He said, the sun is really red
I said, my friend, what do you mean?
You read that in some magazine?
Next thing you'll say the earth's not green
How can I be sure of you?
When you know the world's always changing
Rearranging, always changing, changing
I said, my friend, how do you do
And what you're saying isn't true
The next thing you'll say the earth is blue
He said, my friend, you're in a dream
And things are never what they seem
Oh, things are never what they seem
How can I be sure anymore?
When the world's always changing
Rearranging, changing
