A #26 R and B hit for The Godfather of Soul, "The Spank" was named for a popular dance in 1978. The album Jam/1980's received a B+ review from Robert Christgau:
Free of the pretentious bluster that has marred so much of his work in the disco era, this is the groove album Brown has been announcing for years. He's finally learned how to relax his rhythms without diluting his essence, and the A side is simply and superbly what the title promises, though he may have the decade wrong. The B side is less of the same, and I bet no one who buys this record ever chooses to play it. I also bet they'd get dancing if they did.
