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 (b. 1934), Pervis (b. 1935), Yvonne (b. 1936), and Mavis (b. 1939). They are best known for their 1970s hits “I’ll Take You There”, “Respect Yourself”, and “Let’s Do It Again”.
The family began appearing in Chicago-area churches in 1948, and signed their first professional contract in 1952. During their early career they recorded in an acoustic gospel-folk style with various labels: United Records, Vee-Jay Records (their “Uncloudy Day” and “Will The Circle Be Unbroken” were best sellers), Checker Records, Riverside Records, and then Epic Records in 1965. While the family surname is “Staples”, the group used the singular form for its name, resulting in the group’s name being “The Staple Singers”. Main Source: Wikipedia
