Give Peace a Chance. Lennon was a peace activist and conveyed these sentiments through song, including "Revolution," "Give Peace a Chance," and "Imagine." President Nixon's administration tried to deport him, worried that he would unify the anti-war movement, but Lennon continued to speak out against the Vietnam War.

Lennon and Ono posted billboards proclaiming "War Is Over! If You Want It" all over the world.
All Together Now. All four Beatles were "more agnostic than atheistic" and didn't believe in god. They spoke about their non-belief in interviews in the 1960s, which was very rare at the time. Lennon quoted the Bishop of Woolwich to describe his belief in god "… not as an old man in the sky. I believe that what people call God is something in all of us."
It's in the Bag. Lennon was also a social activist. He wrote a song, "Working Class Hero," about social classes, inequity, and challenging authority. He and his wife, Yoko Ono, developed Bagism, where a person wears a paper bag on their entire body to remove all ways that they could be subject to prejudice and stereotyping. While this idea was satire, the idea succeeded in getting people to think harder about social issues and their own behavior.
Lennon was born in England during an air raid during WWII.

The Beatles were one of the first bands to make music videos.
