Both my grandmothers passed away a few years ago. One of them used to sing, and an aunt recently transferred her album recordings to a cd. So while I work, every now and then my grandmother sings to me through shuffled playlists. I can't think of anything more defining than someone's voice. You hear them singing and your mind's eye creates a vivid portrayal of them, further enhanced by the emotions of the song they are singing. I should create a library of loved ones. I should ask everyone I know to sing their favourite song and record them doing so. I really should.
