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.

Some of the words of Thom starting the band off with a '1, 2, 3' type thing can be heard on the track at the start of part 2. Many fans believe that this track should have made Radiohead's third LP, but in my opinion it should stay as it is. As one of the best b-sides any band would ever record.
