In the glittering peak of the late 1970s disco era, few songs captured the pure, kinetic energy of the dance floor quite like Amii Stewart’s explosive cover of “Knock on Wood.” With its thunderclap drums, soaring vocals, and irresistible groove, the track became a defining anthem of the period—propelling an American singer and dancer from the theater stage to international stardom almost overnight.
From Washington to the West End
Born Amy Paulette Stewart on January 29, 1956, in Washington, D.C., she grew up as the fifth of six children in a large, close-knit, strictly Catholic yet fun-loving family. Her father, Joseph Stewart II, enrolled her in singing and dancing lessons at the age of four. When she later registered with Actors’ Equity Association, she discovered another Amy Stewart was already on the books, so she altered the spelling of her first name to Amii—a change that stuck for life.
Stewart briefly attended Howard University before leaving to focus on dance, training in ballet and modern dance with the Classical Repertory Dance Ensemble (also associated with the D.C. Repertory Dance Company). Her early professional path led her into musical theater. In 1975 she joined the touring company of the Harlem Renaissance revue Bubbling Brown Sugar, performing in Miami, on Broadway, and eventually in London’s West End. It was there that she met songwriter and producer Barry Leng of Hansa Records, a meeting that redirected her career from the stage to the recording studio.
Breakthrough: “Knock on Wood”
Stewart’s first recording, the Leng/Simon May composition “You Really Touched My Heart,” appeared at the end of 1977. Her true breakthrough came with a high-energy disco reinterpretation of Eddie Floyd’s 1966 Stax classic “Knock on Wood.” Released in early 1979, the single raced up the charts and hit No. 1 on the Billboard Hot 100 in April 1979. It earned a platinum certification and a Grammy nomination for Best Female R&B Vocal Performance. The song also performed strongly internationally, reaching No. 6 in the UK and No. 2 in Australia, and has sold millions of copies worldwide.
Her debut album, Knock on Wood (1979), followed and climbed into the U.S. Top 20. The follow-up single, a medley of The Doors’ “Light My Fire” with “137 Disco Heaven,” became another international success, peaking at No. 5 in the UK (though it only reached No. 69 in the U.S.). Stewart’s flamboyant stage presence and striking costumes helped cement her image as a vibrant disco star of the era.
Evolution and Life in Italy
While American audiences largely viewed her as a one-hit wonder after the disco boom faded, Stewart built a more sustained career in Europe. She released further albums including Paradise Bird (1979) and Images (1981, issued in North America in altered form as I’m Gonna Get Your Love). In the early-to-mid 1980s she relocated to Italy, signed with RCA Italiana, and adapted successfully to the local scene.
In 1983 she competed at the Sanremo Music Festival with “Working Late Tonight.” Collaborations with Italian artists followed, most notably the hit “Friends” (with Mike Francis), which became a major European success in 1984–85, and a duet with Gianni Morandi on “Grazie perché.” She also worked with Ennio Morricone, contributing to soundtracks and releasing the 1990 tribute album Pearls – Amii Stewart Sings Ennio Morricone.
Stewart has remained active as a performer, recording artist, and stage actor. Credits include portraying Mary Magdalene in a production of Jesus Christ Superstar and starring as Billie Holiday in the musical Lady Day (which she also helped produce). She has served as a goodwill ambassador for UNICEF Italy and continues to perform, often choosing projects that allow artistic growth rather than pure commercial volume.
Personal Life and Legacy
Stewart married Italian entrepreneur Pietro Cappa in 1994. The couple has long made their home in Sardinia (particularly the Porto Cervo area), a place she has described as a deliberate and fulfilling life choice after years based in major cities. She is the stepsister of singer Miquel Brown and aunt to Brown’s daughter, the singer Sinitta.
Today Amii Stewart is remembered first and foremost for that electrifying 1979 version of “Knock on Wood”—a track that still fills dance floors, appears in films and media (including a portrayal in the movie 54), and stands as a classic of the disco era. Beyond the hit, her story reflects the journey of a trained dancer and theater performer who seized the moment when disco opened doors, then reinvented herself across continents and decades. From Washington stages to European charts and Sardinian home life, Stewart’s career remains a vivid chapter in the history of 1970s popular music.
