The Staple Singers was an American gospel, soul, and R&B singing group. Roebuck "Pops" Staples, the patriarch of the family, formed the group with his children Cleotha, Pervis, and Mavis. Yvonne replaced her brother when he was drafted into the U.S. Army, and again in 1970. They are best known for their 1970s hits "Respect Yourself", "I'll Take You There", "If You're Ready ", and "Let's Do It Again". While the family name is Staples, the group used "Staple" commercially.
