Generation Gap

I bought myself an old Bill Cosby album (vinyl 33 rpm) a few weeks ago. Today, my youngest decides to listen to it while playing video games. I hear the familiar lines of "Noah. Right!"
A little while later, Alex calls down, asking if I have any more Cosby albums. So sorry, just the one. He complains that it was over too soon. That doesn't sound right. He hasn't been up there that long. "Alex? Did you listen to the other side?"
Pause.
"You can listen to both sides?"
