The most embarrassing event in my life was a stage performance that I was to play as the lead pianist. I came in highly recommended and regarded. And this guy was to sing. I had saved my settings on the piano for the guy's performance prior to the time and that was unknown to me. Only for the guy to start singing and I was now searching for my settings and I couldn't find it. The entire crowd were looking at me. The guy had continued singing. And I was busy trying to set the piano. I could only catch up with the guy after he had been singing for like 3 minutes already. That was so embarrassing to me
