I dont have a favorite funeral song, but, I do have a piece for someone to speak. It is the last part of William Cullen Bryants' THANNATOPSIS

So live, that when your summons comes
To join that innumerable caravan
That moves to that mysterious realm
Where each shall take his place in the silent halls of death
Thou go not like the quarry slave at night
Scourged to his dungeon, but, sustained by an unfaultering trust
Approach thy grave like one who wraps the covers of his couch about him
And lies down to pleasant dreams.
