I'm undecided on what song to play at my funeral but an old family friend, after hearing me play The Band tune I Shall Be Released, made me promise to play that song at his funeral.
Years ago my friend's great aunt passed away. His cousin told the family that my friend and him would write a song and play it at the funeral. After a while, they couldn't come up with anything so they called me knowing I write a lot of songs. In about 30 minutes I penned out a tune for them. I never met the woman but I figured writing a song for a funeral would be like shooting fish in a barrel. Throw in a few lines about missing them and some stuff about memories. Kind of a cold mentality I know but it worked. From what they told me, everyone loved the song and was asking for a copy of the lyrics. In hindsight I probably could've made a few bucks off it.
