I also missed the sad news giving rise to this particular themed prize puzzle.
I got off to a slow start with 28 and 13 but once I recognised the theme things started to flow. I enjoyed recalling a couple of the clues referenced in 23 - 14 was a particular favourite and made me chuckle. Agree with Chris and Jono, 15 must be the most famous TV cruciverbalists.
Perhaps surprisingly LOI was 12.
Lovely tribute, enjoyable solve.
Thanks all.
