The World's Not Big Enough is the only solo album by John Du Cann, who was best known as guitarist and vocalist with Atomic Rooster and Hard Stuff in the 1970s.

A group was assembled to record the album, including bass guitarist John McCoy, who later played with Ian Gillan; Liverpool Express and Original Mirrors and future Status Quo drummer Pete Kircher, and keyboard player Andy Bown who was signed to EMI Records but also performed with Status Quo, prior to being a full member in 1982.

The band subsequently performed concerts in London, but Arista ultimately decided not to release the album.

Richie Unterberger of Allmusic described The World's Not Big Enough as "peculiar, though not half-bad, power pop/new wave with a mainstream slant", although he described the bonus tracks as "closer to hard rock in mood".
