(At a rehearsal of "Don Giovanni" the representative of Zerlina
did not act realistically enough to suit Mozart. Thereupon he
went unnoticed on the stage and at the repetition of the scene
grabbed the singer so rudely and unexpectedly that she
involuntarily uttered the shriek which the scene called for. [The
singer was Teresa Bondini, the place Prague, and the time before
the first performance of the opera which took place on October
29, 1787. H.E.K.])
