amy stewart first single was a disco cover version of the 1966 Eddie Floyd hit \"Knock on Wood\" (Floyd/Cropper), reached number one in the U.S. in April 1979, and earned her a platinum record and a Grammy Award nomination. It also reached number 6 in the U.K., and number 2 in Australia, in the same year. It was her only American pop chart hit and as a result she is considered a one hit wonder there although she also achieved several Top 10 and Top 20 hits in the U.S. dance chart. Peter Boita, the well known U.K. session drummer, synced up a Linn Drum Computer to a non click track driven master tape to overdub a much more heavy and contemporary drum beat and sound. Peter then manually overdubbed SImmons SDS7 tom toms using his unique technique of hitting four Simmons pads simultaneously with just two drum sticks! This layering of drum sounds gives the track an enormous depth of sound making the track instantly recognisable after just a couple of opening bars. Peter also overdubbed an 18\" length of suspended hollow scaffolding pole ( originally from the Victoria Palace Theatre in London ) played with two triangle beaters, at Trident Studios in London's St. Anne's Court ( the studio in which Elton John recorded his first album in the early 1970s ). This overdub is not noticeable on the single track ( although it contributes subtly to the overall rhythmic feel ) but is brought to the fore as an intro to one of the later \"mega mixes\" continuing to add a percussive dimension to the whole track. Among her other successes in music recordings, there is the song entitled \"Friends\" in 1985. This song was a collaboration with the Italian composer/music artist Mike Francis and was a big hit in the UK and the Philippines.
