Steinway & Sons 'piano for peace' by DDB Tribal Düsseldorf

To commemorate the event, people can compose their own peace song on the site. On 26 March, the anniversary of the bed-in, the songs were played on a special-edition piano in the suite that Lennon and Ono stayed in.

The work was written by Michael Schilling and Tobias Hecking, and art directed by Fabian Jung, Christian Bültmann and Nadim Habib.
