For my own, I don't know.For others, I have often been asked to sing "May the Work That I Have Done Speak for Me," which is easy to adapt to the facts of the deceased's life and which the entire congregation easily learns and sings along.
May the work that I have done speak for me (2x) If I fall down on this road, Someone else will grab the load May the work that I have done speak for me
May the songs that I have sung . . .
May the battles I have fought . . .
etc.
