By...“The Last Song” I’ve never known much about music.I am the oldest child, so I had no older siblings playing what was popular when I was young. My mother listened to public radio in the morning. My dad played Bach on the piano every Sunday after we got home from church. My parents sang at both services in the church choir, so Mom would make something quick when we got home, often a Swanson pot pie.

His girlfriend, Lou, nodded knowingly and rolled her eyes. I wondered what she was remembering.“And then you stop hearing the song completely!” Andy said. “There is some music I don’t need to listen to anymore,” Clay agreed. “It’s burned into my brain.”I’m not sure if I remember the first time I heard most of the songs I know.
