Mack Rice, composer of "Mustang Sally" and co-writer of "Respect Yourself" has died in Detroit at the age of 82.

Laura Rice told The Associated Press that her husband died at their home Monday of complications from Alzheimer's disease.

"Sir" Mack Rice was best known for writing "Mustang Sally," which was popularized by Wilson Pickett. They had been in a group together called the Falcons.

Rice became a songwriter for Memphis, Tennessee-based Stax Records and split his time between there and Detroit, where he moved as a teen from Mississippi.

He wrote "Respect Yourself" with late R&B singer-songwriter Luther Ingram for the Staple Singers, which became Stax's biggest hit.

Laura Rice and singer Pat Lewis, a longtime friend and collaborator, say he was humble and embodied his other nickname, "Gentleman."
