the tale that Marie Lloyd was criticised/charged/indicted for singing "She sits among the cabbages and peas" so she changed it to "She squats among the cauliflowers and leeks" is funny, and I have heard it told by Ned Sherrin as true. But scholars more knowledgeable insist it is apocryphal. Or the evidence is just not there.

I'm sure she would say such things, but in court?

Another tale from the same source was when a heckler shouted "Show us yer fanny** Marie" to which she replied "Shan't now for asking".
