Lyrically, the title of the song comes from the line "It's the loneliness that's the killer," which occurs only once in the introduction to the Seal version and not at all in the Adamski version.
The song also contains the lyrics "Racism in amongst future kings can only lead to no good, and besides, all our sons and daughters already know how that feels", which were reused in Seal's song "Future Love Paradise" featured on his debut album.
