Lyrically Disadvantage

I have a song and I need the lyrics for it. It might be called ‘Astronaut’ and the information that I have is that it is performed by Thom Yorke (with or without the rest of Radiohead I am unsure) and Ani Difranco is on guitar (this may or may not be true, stylistically similar, but who knows).
It’s a very good song and I would like a look at the lyrics. If anyone knows of this song and a possible source of lyircs please let me know and i will reward you in a manner befitting this dreadful ordeal.
