For many years he worked as a pianist. He had experienced countless performances. What then had been his most uncomfortable experience during his concert tours?

“Once”, he related, “I noticed during a concert that the piano which I was playing was not properly secured. Perhaps the floor of the concert hall was also uneven. While I played, the instrument began to gradually roll away from me. I slid behind it with my piano stool, but it continued to roll. I slid, it rolled. Thus it went on and on, during the entire piece. Most instruments have a brake, which must be secured. If not, then God have mercy on you.”
