“Brick House” from the Commodores came about thanks to the wife of group member William Orange.
The group needed an addition song for their album Commodores, so Orange was assigned to write one.
When he fell asleep trying to come up with something, his wife, also a songwriter, came up with some lyrics about a woman with a great body and left them on a little note pad for Orange to he when awoke.
In the lyrics the phrase “built like a brick house” was originally “built like a brick s**t house,” explaining the horn in the pause between the words ‘brick’ and ‘house.’
It is Orange on the lead vocals, instead of Lionel Richie.
