It's been almost 30 years since the death of John Lennon, who was shot and killed in New York City on Dec. 8, 1980.
And no matter how much time has passed, that date will remain etched in our minds.
But as heart-wrenching as his murder was, Lennon's spirit has lived on through his music and his offspring, including his first-born, Julian Lennon (John's son from his first marriage, to Cynthia Powell).
Now, after more than 10 years, the singer/songwriter is back to making music and putting his genes of a musical genius to work again.
Julian will perform on The Early Show on Dec. 15, the same day, his company, theRevolution (along with James Scott Cook) will release a four-track EP featuring the charity single "Lucy."

The song pays homage to Julian's childhood friend Lucy Vodden, who he drew a picture of and inspired the Beatles classic, "Lucy in the Sky with Diamonds."
The EP also will feature an acoustic version of "Lucy," Cook's new song, "Sober" and Julian's "Beautiful" from his new album, "Everything Changes," which will be released in the spring of 2010.
