Thom Yorke: 'I dreamt I was floating down the Liffey and there was nothing I could do. I was flying around Dublin and I really was in the dream. The whole song is my experiences of really floating'.

Some of the lyrics were inspired by a conversation Yorke had with R.E.M. lead singer Michael Stipe where Stipe suggested he deal with his issues by pulling the shutters down and saying, 'I'm not here, this is not happening'.

A lot of effort went into the string section, which was arranged by Radiohead guitarist Jonny Greenwood and performed by the Orchestra of St. Johns.

Before joining Radiohead, Greenwood considered studying music at the university level and has a talent for working various instruments into a piece. He spent about 2 weeks working on the arrangement, and worked closely with the conductor at the sessions.

'How To Disappear Completely And Never Be Found' is a book by Doug Richmond, released in 1986. It consists of a collection of short stories, always focused on the theme of taking French leave.
