Throughout the day, 6 Music played the music that inspired Lennon in John's Jukebox , featuring tracks from Chuck Berry, Gene Vincent, The Isley Brothers, Little Richard, Buddy Holly, and Bob Dylan.
And from the music that influenced Lennon, to the musicians who were inspired by him. Paul Weller, Duke Spirit, and Cornershop were amongst the artists who contributed exclusive cover versions of Lennon songs for 6 Music, while Alex James , Dandy Warhols , JJ Burnell, Roisin Murphy, and Guy Garvey joined celebrities like David Walliams, Rob Brydon and Martin Freeman to nominate their all time favourite John Lennon song.
6 Music's Andrew Purcell reported from the vigil held in Strawberry Fields, Central Park in New York, talking to the Lennon fans gathered to pay their respects.
The death of John Lennon was a defining moment for a whole generation of music fans, and 6 Music listeners will share their memories and tell where they were when they heard the news on the 6 Music Website.
Finally, Yoko Ono talked exclusively about her life with John in Yoko Ono: In Her Own Words in which she talked about the first time she met John, their early collaborations, John's plans for the future at the time of his death, and what his view of the world - from Iraq to the internet - would be if he was with us today.
