Nanny Ogg's bath night, as described in the novel "Lords and Ladies", is an event feared by the entire population of Lancre, chiefly because she sings any and all of the above songs, accompanied by banjo, whilst bathing, and the tin bath amplifies her already overpowering vocal presence such that the audience is not so much "captive" as "hunted down". Residents of Lancre tend to hide their livestock at this time as well, as the trauma causes the sheep and goats to "give yogurt for weeks" afterwards. This event usually occurs once a year, so everyone has plenty of time to prepare.
