John Lennon's legacy continues to be explored through newly uncovered demos, reflections from his son Giles Martin, and ongoing cultural references in music and film. Recent tributes include a 1988 U2 release, a posthumous hit single, and a tribute by George Harrison, while personal milestones such as the birth of Lennon’s first grandchild are also noted. His 1970 album, influenced by therapy sessions, and his iconic song 'Imagine,' released 55 years ago, remain central to his enduring influence.
