Which 1979 disco single by Amii Stewart was adapted from a song by Eddie Floyd?

Amii Stewart’s 1979 disco single “Knock on Wood” was adapted from a song by Eddie Floyd.

Floyd and Steve Cropper wrote the original “Knock on Wood,” which was recorded by Floyd in 1966 as a Stax soul single. Stewart’s version transformed the composition into an extended disco arrangement, adding a faster dance pulse and a prominent orchestral sound.

Her recording became a major international hit. It reached number six on the US Billboard Hot 100 and topped the charts in several countries. The performance made Stewart an important disco-era vocalist and introduced the song to a new pop and dance audience.

The title is sometimes mistaken for an original Stewart composition. It is instead a disco reworking of a 1960s soul standard, illustrating how disco artists frequently recast earlier R&B material for club culture.
