A pianist has played Imagine by John Lennon at the memorial in Birstall where MP Jo Cox was killed.
Davide Martello brought his piano to the West Yorkshire village because he "wanted to give a contribution for peace".
"Unity is very important all over the world", the pianist from Germany said, adding that it makes us all "stronger" and that "music can connect people" no matter what their race, religion, or class.
Mr Martello laid flowers at the scene before attaching the piano to his bike and cycling away.
In November Mr Martello took his piano to the Bataclan theatre following the Paris terror attacks, where again he played Imagine.
Rev Paul Knight said the Labour MP was a 'fervent advocate for the poor and oppressed'.
