Sir Elton Hercules John CBE (born Reginald Kenneth Dwight) is an English pop/rock singer, composer and pianist.

In his five-decade career, John has been one of the dominant forces in rock and popular music, especially during the 1970s. He has sold more than 300 million albums and over one hundred million singles, making him one of the most successful artists of all time. He has won five Grammy awards and one Academy Award. His success has had a profound impact on popular music and has contributed to the continued popularity of the piano in rock and roll. In 2004, Rolling Stone ranked him #49 on their list of the 100 greatest artists of all time.

Some of the characteristics of John's music are his ability to quickly craft melodies for the lyrics of songwriting partner Bernie Taupin, his former rich tenor (now baritone) voice, his classical and gospel-influenced piano, the aggressive orchestral arrangements of Paul Buckmaster among others and the flamboyant fashions and on-stage showmanship, especially evident during the 1970s.

John was inducted into the Rock and Roll Hall of Fame in 1994. He has been heavily involved in the fight against AIDS since the late 1980s and was knighted in 1998.
