Simon decides after glancing at Jonathan in particular that his audition is going to be subpar the moment he

and Charlotte step onto the ‘Britain’s Got Talent’ stage. He says to his fellow judge, ‘Just when you think it couldn’t get any worse.’ in a low voice.

Simon had no idea that this audition from 2012 would go on to become one of the most well-known on YouTube, and for the most positive reason possible.

In the video below, Charlotte and Jonathan perform a pop-opera hybrid of ‘The Prayer.’ However, Jonathan’s talent and confidence come to the fore when he displays his amazing operatic voice.

Simon’s mouth drops, and when he finally gets around to criticizing the pair, his remarks totally contradict what they had thought at first.

You can watch the incredible performance as well as the jury’s closing remarks in the video that follows.
