Thanks Buddy, it's not in the Chambers app but it does come up in Google.
Thanks Malone, I'm about half-way through but finding it more difficult than this week's Listener ...... or maybe I was just distracted by the misprint that wasn't 🤔😜

I found this alright, but probably wouldn't have got 12d without the theme's surname - so I did the last bit before I completed the grid. Is that allowed?
Biggus, I often do the end before the middle! Sometimes I can do a few remaining clues only because thematic bits, elements, letters help fill in some cells.
