Long, long time ago I had a big gig at some festival on half open stage, and the wind was there. My place on stage was right besides the most popular piano player of our country, 90 years old man, called Maestro. I was playing from the notes and suddenly wind got hard and took a few lists away, i was shocked and run for them to prevent the situation and continue to play. It took about 4 seconds without me and then Maestro turned to me and said - "how can it happen ???". I was in bad mood that day.
