The Main Ingredient

The Main Ingredient is an American soul and R&B group best known for their 1972 hit song "Everybody Plays the Fool".

The group was formed in Harlem, New York City in 1964 as a trio called the Poets, composed of lead singer Donald McPherson, Luther Simmons, Jr., and Panama-born Tony Silvester. They made their first recordings for Leiber & Stoller's Red Bird label, but soon changed their name to the Insiders and signed with RCA Records. In 1968, after a couple of singles, they changed their name once again, this time permanently, to the Main Ingredient. The name came from a Coke bottle.
