Thank you Ariadne and dancing gran 
Instead of a prayer at John's funeral, I asked the Minister to read out this which has given me, and the girls too, comfort since he died (the longer version from Nicholas Evans):
If I be the first of us to die
Let grief not blacken long your sky
Be bold yet modest in your grieving
There is change but not a leaving.
For just as death is part of life,
The dead live on forever in the living.
For all the gathered riches of our journey
The moments shared, the mysteries explored,
The steady layer of intimacy stored.
The things that made us laugh, or weep or sing,
The joy of sunlit snow, of first unfurling of the spring.
The wordless language of look and touch,
The knowing,
Each giving and each taking,
These are not the flowers that fade.
Nor trees that fall and cumble.
Nor are they stone
For even stone cannot the wind and rain withstand,
And mighty mountain peaks in time reduce to sand.
What we were, we are.
What we had, we have,
A conjoined past imperishably present.
So, when you walk the woods where once we walked together
And scan in vain the dappled bank beside you for my shadow,
Or pause where we always did upon the hill to gaze across the land,
And spotting something, reach by habit for my hand
And finding none, feel sorrow start to steal upon you;
Be still,
Close your eyes,
Breathe.
Listen for my footfall in your heart
I am not gone, but merely walk within you.
