There seem to be people who remember the Heike Monogatari line "The bells of Gion Shoja, the voice of the bells, resound with the impermanence of all things" as "the sound of the bells of Gion Shoja" rather than "the voice of the bells". Also, there is a note that "ogoreru mono hisashikarazu" (the proud mono do not last long) has changed to "ogoreru hito hisashikarazu" (the proud hito do not last long).
