This opens as a short acoustic number (part 1) before blowing up into an incredible rock song. Recorded at Radiohead's Bath studios along with the rest of OK Computer, this song very nearly made it on to the album. The lyrics perpetuate Thom's health fixation, but the actual meaning of the song isn't clear. There is much debate about the actual words in Part One, and when questioned, Thom just laughed and said he couldn't actually remember.
