A current thread is called 'naughty' songs &c [NB the quote marks]. Another commonly used term is 'bawdy'. Bert Lloyd, as I had to define after quoting it to another regular [American] poster who didn't quite understand what he meant by it, used to call such songs 'disobliging'. As I mentioned in the same post, a source singer had to be much persuaded by the early collector Priscilla Wyatt-Edgell to sing her a certain song, as it was, he thought, unsuitable for a lady's ears, being, in his words 'outway rude'.

Can anyone think of any other adjectives or euphemisms used to describe the sort of song I obviously have in mind?
