Harris was introduced to Richard in 1958 and was credited with coming up with the name The Shadows.
With The Shadows, Harris enjoyed a string of hits in the late 1950s and early 1960s including High Class Baby, the chart-topping Apache and Guitar Tango.
His last recording with the band was Wonderful Land in 1962, which also made it to #1 in the British charts.
After leaving the group, Harris teamed up with former Shadows band-mate Tony Meehan and again reached number one with Diamonds in 1963.
After a serious car crash nearly ended his career he faded from the limelight, although he did tour in Europe and release several albums.
As his success as a musician faded, Harris became a professional photographer and was awarded an MBE for his services to music.
Harris died, aged 71, in March 2011 after a two- year battle with cancer.
“Jet was exactly what the Shadows and I needed – a backbone holding our sound together,” Cliff Richard said in a statement. “Jet, the bass player, will always be an integral part of British rock ‘n’ roll history. Losing him is sad – but the great memories will stay with me. Rock on, Jet.”
