Good Lord, I don't know how I would react if I went to a funeral where they played Always Look on the Bright Side of Life. The whole absurdity of it makes me want to laugh just thinking about it. Since the funerals on one side of my family sometimes have a bit a self-deprecating humor in them, I guess it shouldn't strike me as such an odd song.
I already asked kin folk to play Na Na Na Hey Hey Hey Goodbye (Steam version from 1968), but made My Way (Sinatra version) optional as well...
