Mercy, Mercy (Don Covay song) Mercy, Mercy (Don Covay song) "Mercy, Mercy" (sometimes referred to as "Have Mercy") is a soul song first recorded by American singer/songwriter Don Covay in 1964. It established Covay's recording career and influenced later vocal and guitar styles. The songwriting is usually credited to Covay and Ron Alonzo Miller, although other co-writers' names have also appeared on various releases. In late 1964, the song became a hit, reaching number one on the "Cash Box" R&B chart and number 35 on the "Billboard" Hot 100. Several artists have recorded "Mercy, Mercy", including a well-known version by the Rolling Stones in 1965.
