Gregory Stuart Lake (10 November 1947 – 7 December 2016) was an English singer, songwriter, bassist, guitarist and record producer. He gained prominence as a founding member of the progressive rock bands King Crimson and Emerson, Lake & Palmer (ELP).
Born and raised in Dorset, Lake began to play the guitar at the age of 12 and wrote his first song, "Lucky Man", at the same age. He became a full-time musician at 17, playing in several rock bands until his friend and fellow Dorset guitarist Robert Fripp invited him to join King Crimson as lead singer and bassist. They found commercial success with their influential debut album, In the Court of the Crimson King (1969). Lake left the band in 1970 and achieved significant success in the 1970s and beyond as the singer, guitarist, bassist, and producer of Emerson, Lake & Palmer (ELP). As a member of ELP, Lake wrote and recorded several popular songs including "Lucky Man" and "From the Beginning". Both songs entered the UK and US singles charts.
Lake launched a solo career, beginning with his 1975 single "I Believe in Father Christmas" which reached number two in the UK.
