“Brother Louie” by Stories is a classic early 70’s tune that went to #1 for two weeks in the summer of 1973. Here’s more about the song from Wikipedia:
“Brother Louie” is a song about an interracial love affair between a white man and a black woman, and the subsequent disowning of the man by his parents because of it. The title was written and sung by Errol Brown and Tony Wilson of the group Hot Chocolate, and was a No. 7 hit in the UK Singles Chart for the band in 1973, produced by Mickie Most. Alexis Korner has a spoken word part in this version of the song, Phil Dennys arrangement of the string section.
Here’s a great LIVE performance of “Brother Louie” from The Midnight Special in 1973.
