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 name is Staples, the group used "Staple" commercially. 　　Roebuck moved from Mississippi to Chicago after his marriage, and worked in steel mills and meat packing plants while his family of four children grew up. The family began appearing in Chicago-area churches in 1948.Their first public singing appearance was at the Mount Zion Church, Chicago, where Roebuck's brother, the Rev. Chester Staples, was pastor. They 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. "Uncloudy Day" was an early influence on Bob Dylan, who said of it in 2015, "It was the most mysterious thing I'd ever heard... I'd think about them even at my school desk...Mavis looked to be about the same age as me in her picture (on the cover of "Uncloudy Day")...Her singing just knocked me out...And Mavis was a great singer—deep and mysterious. And even at the young age, I felt that life itself was a mystery." 　　The Staples move to Epic saw a run of albums, including the live in-church Freedom Highway album produced by Billy Sherrill; the title track of which was a civil rights movement protest song penned by Pop Staples. It was on Epic that the Staple Singers developed a style more accessible to mainstream audiences, with "Why (Am I Treated So Bad)" and "For What It's Worth" (Stephen Stills) in 1967. In 1968, the Staple Singers signed to Stax Records and released two albums with Steve Cropper—Soul Folk in Action and We'll Get Over, Pervis returning for them. After Cropper left Stax, Al Bell produced their recordings, conducting the rhythm sessions at the famed Muscle Shoals Sound Studio and cutting the overdubs himself at Memphis's Ardent Studios,moving in a more funk and soul direction.
