The song earned a Grammy Hall of Fame Award and an induction into the Rock and Roll Hall of Fame's 500 Songs that Shaped Rock and Roll. Dozens of artists have performed or recorded versions of "Imagine", including Madonna, Stevie Wonder, Joan Baez, Elton John and Diana Ross. 

John Winston Ono Lennon, MBE (9 October 1940 – 8 December 1980) was an English singer, songwriter, musician, and peace activist who co-founded the Beatles, the most commercially successful band in the history of popular music. He and fellow member Paul McCartney formed a much-celebrated songwriting partnership. Along with George Harrison and Ringo Starr, the group would ascend to world-wide fame during the 1960s.  In 2002, Lennon was voted eighth in a BBC poll of the 100 Greatest Britons and in 2008, Rolling Stone ranked him the fifth-greatest singer of all time. In 1987, he was posthumously inducted into the Songwriters Hall of Fame.
