I second Sandy with 'Turning Towards the Morning', but this song by Si Kahn is also very moving:

MEMORIAL
(Si Kahn)

We come today to say goodbye
To one who has held us close
To tell the stories of his life
That move us each the most
These memories of a life well lived
And of a death well faced
Are now a part of every life
That crosses in this place

Refrain:
No circle has been broken here
No one that stands alone
The threads of life, so lately broke
Are woven through our own

He'd hoped to meet us all again
That gather here today
But though we will not meet again
We'll meet again some way
In work we do, in songs we sing
In courage and in pain
In battles that we fight as one
We'll see his face again

Repeat refrain
