Like '2+2=5', this song was inspired by Thom Yorke's compulsive tracking of BBC Radio 4 news bulletins.

This track was particularly inspired by his habit of walking in the countryside with a portable radio.

According to Q magazine April 2008, the lyric about 'Yesterday's headlines blown by the wind' was derived from a passage in Thomas Pynchon's 1963 novel V, about the search for a mysterious vanished woman.
