And fans can say Yoko Ono broke up the Beatles all they want–because, well, she was involved–but the fact remains that she and John Lennon held some of the most peaceful protests ever witnessed in history.

One such event was their “bed-in” in 1969, during which they did interviews from their bed in Montreal promoting peace. They also recorded one of the most monumental tracks about peace in our time that week–the unforgettable “Give Peace a Chance,” still played today at protests, vigils, and peace rallies worldwide.

Today Yoko Ono and Sean and Julian Lennon are extending the peaceful notions generated by their song in a way that modern people, untouched by (or having forgotten) the sixties, can understand–they’re using it to raise money.

A 40th anniversary digital single of “Give Peace a Chance,” officially by John Lennon and the Plastic Ono Band is available for downloading at iTunes for $1.29. All net proceeds will go to the United Nations Peacebuilding Fund.

“It is indeed a time when we are all getting more aware of the necessity of doing something to achieve world peace, no matter how small. I feel deeply that we are all one, regardless of where we stand,” says Ono.

They’ll be doing it with pinwheels.

An estimated 3 million peaceful pin-wheelers will be spinning their colorful creations on Monday. As a nonpartisan, nonpolitical effort, the activity is designed to raise awareness about not just peace, but the violence we’ve become so accustomed to in our lives.

As The Pinwheels for Peace Project says, peace needs to become more than just a word. According to their website, peace “comes down to a simple definition: a state of calm and serenity, with no anxiety, the absence of violence, freedom from conflict or disagreement among people or groups of people.”

Pointing out that peace isn’t just about the absence of war, the project is a movement for tolerance, harmony, cooperation and unity–an effort to put an end to the daily intolerance and violence in our lives.

Many people will be participating by adding their definitions of peace, or the word peace in different languages, on their pinwheels. Pinwheels will be used as decorations, toys, and distributed items throughout different countries of the world.

As a childhood symbol of more joyful times, pinwheels were selected as the sigil of the day. Since they are easily made, accessible, and simple to use, they are a universal “toy” the world can connect with and share in the simplicity of just being–peacefully, without judgement–much like a child would.
