My first thought was:
Clip 1 is Europe 97 and clip 2 was Japan 2000.
Then, I assumed clip 2 was NOT First Tube.
Next, I figured clip 1 was a jam tune, so I started with Ghost (because of that Lakewood release), and listened to a few long ones I hadn't heard in a while.
Around 1am, I realized clip 1 was Cavern, and vaguely remembered the Ireland version, and confirmed it by listening.
Finally, I looked over the Japan setlists, and there was a Cavern with the First Tube like ending, which I vaguely remember. And I did listen to the end part up until where I thought clip 2 begins and just assumed I had found the clip.

So, I too, did not listen to fifty Caverns. Just some quality 97 Europe stuff. Keep 'em coming.
