When a Nearby Train Becomes Part of the Loop

I wanted to wait for this train to pass, as it was very loud. But it was also rather long, so I played my next song ("Finger on the Pulse"). I didn't expect the train to be so loud that it would be this audible in the loop. But I liked it, so I decided to record the ending.
People sometimes don't believe that I perform everything live at my shows, so this was a nice way to give evidence that it's all live.
