A live favourite, Radiohead used "The National Anthem" to start all of their shows on their relatively small Kid A tour.

The song features a mesmerizing bassline which continues unaltered throughout the track. This was played by Thom for the recorded version of the track, but obviously Colin (being the bassist) plays it live.

Thom also uses more voice distorting effects as in Kid A, but they are slightly clearer this time around.

The Orchestra of St.Johns conducted by John Jubbock and scored by Jonny Greenwood. Hook horns blown: Andy Bush [trumpet], Steve Hamilton [alto], Martin Hathaway [alto], Andy Hamilton [tenor], Mark Lockheart [tenor], Stan Harrison [baritone], Liam Kerkman [trombone], Mike Kearsey [bass trombone]. Rhythm sampling by Henry Binns.

The National Anthem is the most energetic track on the album, containing Thom literally screaming lyrics, which are drowned in spooky electronic howls, Phil's drum loops, and Colin's amazing bassline. Not to mention the very original brass band who dominate the song. Thom said he was aiming for a controlled chaos, similar to that of Charles Mingus. He was sat conducting a brass band in the studio, basically letting them hit whatever notes they wanted, but instructing them when to play. This gives a very strange sounding, and chaotic centre to the piece. Unfortunately, when played live, some of this chaos is lost as the brass band doesn't accompany Radiohead on tour.

Originally known as 'Everyone', a part of the real National Anthem can be heared towards the end, with Thom shouting 'Turn it off!' This track was originally considered for an OK Computer b-side.
