The IMAGINE Piano Peace Project

There's little I can add about this subject that isn't being told better by Steve himself.

So, I'll give you a little taste or two and let you follow links to get it right from the source.

when Caroline True from the IMAGINE Piano Peace Project contacted her and said
they wanted to put John Lennon's piano in her home to take a photo of it for a souvenir album, Gabi insisted they contact me and allow me to participate.They're bringing the piano to places of violence and taking photos of the IMAGINE piano in these places in order to bring attention to these acts of violence. They will be making a photo book and are also shooting a documentary of the process.

George Michael bought the Lennon piano at an auction in October 2000. Considered
the most expensive piece of pop memorabilia, experts have estimated its value at US$8 million to $12 million. Michael and his partner, Kenny Goss, owner of Goss
Gallery in Dallas, want to further strengthen the project’s peaceful message, by having “Imagine” performed on the piano at each stop. A video documentary and a
published volume of the images are under development, with plans to donate
proceeds to charity.

When I spoke with Caroline True, the creative director of the Imagine Piano Peace Project, about the event, she said they try to not plan too much, but to simply let the moment happen. Put the piano in the place of violence and just let it speak for itself. Let the people do what they will do. The mere fact of this piano in this place is what
is really powerful. The poetry of it is overwhelming. The sound of this little
instrument inspired a great and meaningful anthem to peace.

You have to read the rest for yourself. Nothing I could add would improve on Steve's own words.
