Which 1978 disco song by Amii Stewart was a cover of Eddie Floyd’s 1966 soul hit?

Amii Stewart’s 1978 disco song “Knock on Wood” was a cover of Eddie Floyd’s 1966 soul hit.

Eddie Floyd and Steve Cropper wrote the original “Knock on Wood,” which Floyd recorded for Stax Records in 1966. Amii Stewart’s later version transformed the song into an expansive disco performance, adding a faster rhythm, prominent orchestration and a vocal style suited to late-1970s clubs.

Released in 1978, Stewart’s version became an international success. It reached number one on the U.S. dance chart and became her signature recording, while also reaching the Top 10 of the Billboard Hot 100.

The song is often linked with other disco covers of earlier soul material, but its lineage is specific: Stewart’s recording reinterpreted Floyd’s Stax classic rather than originating as a new disco composition. The phrase “knock on wood” itself is an English-language superstition, but the chart hit refers to the named song and its disco arrangement.
