Not on the same scale, but I've found having screwed up badly in the past helps me keep my calm in the present. My favorite example: about twenty years ago I accidentally played a note during a grand pause (the entire orchestra silent) in the first movement of Beethoven's Fifth. In concert, at Hill Auditorium. That's one of the worst musical mistakes possible, in the one piece of classical music almost everyone knows, in what is almost certainly the nicest concert hall I will ever get to play in.
Ever since then when getting ready for a concert where I'm not the soloist, I can just tell myself "What can I possibly do wrong that would be worse than that?" and the tension goes away.
