An all-star benefit concert in honour of the former Beatle is scheduled for November 12 at New York’s Beacon Theatre, with a lineup that includes Jackson Browne, Aimee Mann, Shelby Lynne, Patti Smith and Cyndi Lauper.
Proceeds will go to the Playing for Change Foundation, which promotes peace with music.
The musician was killed 30 years ago, just two months after turning 40.
On Lennons actual birthday his widow Yoko Ono plans to be in Iceland, at the Imagine Peace Tower, an outdoor art piece that she designed and dedicated to her husband back in 2007.
The tower, which is located on Viðey Island (near Reykjavík), is made up of 15 spotlights which are projected upwards from a white stone monument that has the legend Imagine Peace inscribed on it in 24 different languages.
Ono is also planning to play at a number of tribute concerts herself, with her We Are Plastic Ono Band in Los Angeles. Among the other acts expected to perform are Lady Gaga and Iggy Pop.
In addition, Ono is also planning to re-release eight of Johns solo albums as well as a new collection of his work.
Earlier this month Lennons murderer, Mark David Chapman, was denied parole for the sixth time.
