Written by the Isleys as a group effort, this song is an open-hearted call for equality across the planet. Guitarist and principle lyricist, Ernie Isley, told Uncut: "Harvest For The World refers to a peaceful gathering where every human being is invited, and where no-one will be hindered in any way from participating."

Keyboardist Jasper Isley added: "At that time, Vietnam had just ended, a lot of people were still missing in action, the economy wasn't great. It was like it is now, there was a big difference between the 'haves' and the 'have-nots.' That's kind of what this song is talking about, asking a rhetorical question, 'When will there be a harvest for the world?' When will there a time that people have an equal share of what's going on, when will they have equality in their lives? Basically we know – the return of Christ, that's when it's going to be, because he's a God of equality so that's when it will ultimately occur. But the song is just asking that question."

A cover released by Liverpool group The Christians reached #8 in the UK in 1988, two places higher than the original. All proceeds from their version went to charity.

The Christians' version featured an animated video created by four leading animation companies, including Aardman of Wallace and Gromit fame, which won several awards.
