I agree with steenkh about not being able to appreciate your own funeral since I don't believe in an afterlife, either. Still, I want my funeral to reflect what I stood for. And I want the music to tell my loved ones what I felt about them. So I've already told everyone I want "Old and Wise" by The Alan Parsons Project.
Some of my favorite lines:
And to those I leave behind
I want you all to know
You've always shared my darkest hours
I'll miss you when I go
And someday in the mist of time
When they ask you if you knew me
Remember that you were a friend of mine
As the final curtain falls before my eyes
For some reason, these words always move me. I can't hear the song without tearing up, and just typing them in gave me chills!
(A curious anecdote: A few years ago, I was at the lake with my husband and we were preparing for our final night dive to get our Advanced Diver certification. I had had a very bad experience on my very first night dive the night before but was determined to overcome the fear. As we were gearing up in the parking lot, another diver pulled up in her car and that song was playing on her CD player. I looked at my husband and he knew what I was thinking right away. OMEN!!! Of course, I don't believe in omens, but it was still creepy, hearing my funeral song playing as I was preparing to do something I thought might kill me. Anyways, all turned out well, obviously. I completed my certification and have no problem night diving at all now.)
