Despite being approached by various artists during their career So Hard (The KLF vs Pet Shop Boys) is one of the very few remixes Bill and Jimmy did of other people’s tracks.
The story behind the single’s B-side, the ambient UFO remix of It Must Be Obvious, is just as strange, as Chris Heath recalled in Details in 1991.

The original UK release of So Hard (KLF vs PSB) was issued as 12″ single only. A CD5 version was released in Germany the same year.
An image shared by @petshopboysstudio on Instagram in November 2022 suggests that addditional versions had been commissioned but remain unreleased, including an extended version and dub mix (all reportedly similar to the commercial version).
