Leo Graham and Paul Richmond, record producers, were nominated for a Grammy for this 1980 hit song, the biggest by The Manhattans for several years - their second and final trip to the Billboard top 5 (although they'd continue to be the R&B chart hitmakers they had been for more than a decade).
But hey, that's not the point of this post. The point is to make sure you know it's The Manhattans, and not Earth, Wind, and Fire, who perform this song. Yes, EWF has a song by the same name. It's not this song.
