The song in Rico's head

It's Threshold of a Dream by the Moody Blues:

I think
I think I am
therefore I am
I think

Of course you are, my bright little star
I've miles and miles of files
pretty files of your forefathers fruit
and now to suit
Our great computer
you're magnetic ink

I'm more than that
I know I am
at least, I think I must be

There you go man
keep as cool as you can
Face piles of trials with smiles
It riles them to believe that you perceive
the web they weave
so keep on thinking free
