We sing for peace, join hands and raise your voice
In friendship stand with those who have no choice
Unite in song, wish for a safer world
A oes heddwch? Dymunwch am heddwch

This is a verse from the Peace Anthem sung by 700 strong voices at the 2013 Street Choir Festival held in Aberystwyth last weekend.

The Welsh translates - roughly - as;
Will there be peace? We all pray for peace

It applies equally to those with cares who need peace of mind. I hope it may help.
