The Staple Singers were an American gospel, soul and R&B singing group. Roebuck "Pops" Staples (1914–2000), the patriarch of the family, formed the group with his children Cleotha (1934–2013), Pervis (b. 1935), and Mavis (b. 1939). Yvonne (b. 1936) 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 (Come Go with Me)", and "Let's Do It Again", which with one exception ("I'll Take You There") peaked on the Hot 100 within a week from Christmas Day. While the family surname is "Staples", the group used the singular form for its name, "The Staple Singers".
