Cranbrook as a setting for While Shepherds Watched pre-dates the song Ilkley Moor Baht'at.

There are many versions of While Shepherds watched in the Sheffield carolling tradition alone - 6 or 7 in the book produced by Ian Russell.

Less celebrated is the number of different versions of Hark Hark What News there are. Obviously it isn't as popular a carol as While Shepherds out in the wider world, so perhaps that's why it's less noted. But it does give some insight into the fact that carols were probably sung to many different tunes at one time, and not just their "standardised" versions. Maybe this is because the words came from broiadsheets, and a tune was selected to fit? Or maybe there was a less fixed notion of how the carols were "supposed" to sound, so there was more freedom for a village musician to introduce a tune they thought fitted the words better.
