Kennedy began his musical career in bands in his native Rotherham and progressed into audio engineering and production. It was his production on the 1993 Lulu song Independence that kick started his career before going full throttle in handling the careers of artists on the pop landscape throughout the 90’s and beyond including Take That, Blue, Five, S Club 7 and Bryan Adams. He wrote for the Spice Girls and helped deliver one of their Number 1 UK singles, Say You’ll Be There.

Kennedy, alongside Gary Barlow, wrote the soundtrack to the Finding Neverland musical comprised of 22 songs that superbly capture the spirit of the production.

In 2006 he delivered the song Never Gonna Break My Faith’ for Aretha Franklin, a duet with Mary J Blige and the Boys Choir of Harlem that was featured in the Emilio Estevez directed film Bobby about the last moments of Robert F Kennedy. Co-written with Kennedy’s long term associate Bryan Adams, the song was awarded a Grammy Award for Best Gospel Song in 2007 and nominated for the Golden Globe Award for Best Original Song. It had a further moment when it was used to accompany footage visualising the American human rights movement.
