John Lennon

Today, December 8th, marks the 35th anniversary of John Lennon's death. The late Beatles star was killed just outside of his apartment building in New York City after being shot by Mark David Chapman on December 8th, 1980 at the age of 40.

Although he had a successful career with the Beatles, he also left quite a legacy with his solo career. And although we have a lot of great music to remember him by, most notably, we remember "Imagine." The song received a Grammy Hall of Fame Award in addition to an induction into the Rock and Roll Hall of Fame's 500 Songs that Shaped Rock and Roll.

"Imagine" was inspired by several poems from Yoko Ono's 1964 book Grapefruit. In a 1980 interview with Playboy, Lennon said of the song:

"The concept of positive prayer ... If you can imagine a world at peace, with no denominations of religion - not without religion but without this my God-is-bigger-than-your-God thing - then it can be true ."

The song's lasting effect has found its way into the voices many of today's biggest artists, as they have continually covered the track over the years in concert and special performances. Check out some of the best "Imagine" covers below:

Willie Nelson recently shared his cover of the song just before the "Imagine: John Lennon 75th Birthday Concert"
