Here is Michael Kelly's account of the same event: "With all her great skill and knowledge of the world, Madame Mara was induced, by the advice of some of her mistaken friends, to give a public concert at the King's Theatre, in her seventy-second year, when, in the course of nature her powers had failed her. It was truly grievous to see such transcendent talents as she once possessed, so sunk--so fallen. I used every effort in my power to prevent her committing herself, but in vain. Among other arguments to draw her from her purpose, I told her what happened to Monbelli, one of the first tenors of his day, who lost all his well-earned reputation and fame, by rashly performing the part of a lover, at the Pergola Theatre, at Florence, in his seventieth year, having totally lost his voice. On the stage, he was hissed; and the following lines, lampooning his attempt, were chalked on his house-door, as well as upon the walls of the city:-- _'All' eta di settanta Non si ama, ne si canta.'"_ W. T. Parke, forty years principal oboe player at Covent Garden Theatre, is kinder to Madame Mara in his "Musical Memoirs," but it must be taken into account that he is kinder to every one else, too. There is little of the acrimonious or the fault-finding note in his pages. This is his version of the affair: "That extraordinary singer of former days, Madame Mara, who had passed the last eighteen years in Russia, and who had lately arrived in England, gave a concert at the King's Theatre on the 6th of March (1820), which highly excited the curiosity of the musical public. On that occasion she sang some of her best airs; and though her powers were greatly inferior to what they were in her zenith, yet the same pure taste pervaded her performance. Whether vanity or interest stimulated Mara at her time of life to that undertaking, it would be difficult to determine; but whichsoever had the ascendency, her reign was short; for by singing one night afterwards at the vocal concert, the veil which had obscured her judgment was removed, and she retired to enjoy in private life those comforts which her rare talent had procured for her."
