Well, we have you covered! There’s a replay HERE, behind that clicky link there. (Or click on the screengrab, same difference.)
When you get there, click on the “REPLAYS” tab. You’ll see a bunch of videos to replay–for the one with actual sound, click on the one that is 29:37 long. And that’s it!
(And if you missed it, you DO want to listen to the replay–they sang “Diamond Dreams” and “Automatic”!)
