Merry Clayton is an American soul and gospel singer. She contributed vocals to numerous tracks and worked with many major recording artists for decades, including a duet with Mick Jagger on the Rolling Stones song "Gimme Shelter". Clayton is prominently featured in 20 Feet from Stardom, the Oscar-winning documentary about background singers and their contributions to the music industry.

"It's in His Kiss" is a song written and composed by Rudy Clark. It was first released as a single in 1963 by Merry Clayton that did not chart. The song was made a hit a year later when recorded by Betty Everett, who hit No. 1 on the Cashbox magazine R&B charts with it in 1964. Recorded by dozens of artists and groups around the world in the decades since, the song became an international hit once again when remade by Cher in 1990.
