Luckily, the story runs in The Daily Mail.

Therefore, it is physically impossible for it to be true...

I suppose folk songs go the same way as cigarette advertising. If it can be shown to be heritage rather than commercial, it is ok. Hence Edwardian cigarette adverts on metal sheets can still be put up as decorations in pubs

Presumably, traditional songs fall into the same category, if the PC brigade have a go?

(When I look at some of the comedy songs I used to sing over the years, such as The Vicar & the Frog, you wonder what you could be accused of promoting!!)
