The Day the World Turned Day-Glo

Released on EMI International in March 1978 with I Am a Poseur on the B-side, it reached number 23 in the UK. It closes the second side of the album. Ted Bunting plays saxophone on it.

Pitchfork's Jenn Pelly says the song has an ominous gravity but is catchy, and that its list of synthetic things, perspex window panes, the acrylic road, a polypropylene car, a rubber bun, ends on trees whose leaves are synthetic fiber. She writes that it anticipated the anxieties of a world made of hidden chemical detritus. Charles Shaar Murray of NME called it immortal in his 1978 review of the album, and Trouser Press named it with Warrior in Woolworths as the kind of title that sums up Styrene's focus on the artificiality of modern life.
