Back in 2015, I published an article about paratext. About teaching music students the importance of paratext, to be accurate. But my title was too flippant – evidently “double entendre” belongs between friends, but not in a contents page! It didn’t attract as much attention as it deserved, possibly for that reason.
Nonetheless, I still think it was a good article. Pity I can’t retrospectively change that title, though!
