Times Quick Cryptic No 2023 by Joker

I have indicated my WOD below, and I award my COD to 19a for reminding me of my dad’s final joke just before he ‘crossed the bar’ a few years ago.  After pleading for months for some Dandelion and Burdock (an unusually flavoured soft drink once popular in the Midlands), I finally tracked some down and took it to him in his care home.  When I handed it to him, he took one look and said ‘Can’t stand the stuff!’.  God bless him!

ONE – E{nglish} N{ational} O{pera} reversed (on retirement).
12  Wild growth in free line dance (9)
CELANDINE – Anagram (free) of [LINE DANCE].  The CELANDINE is either of two plants (the Greater or Lesser CELANDINE) which legend has it will flower when the swallows come, and perish when they depart.  Not known to me, but gettable from the anagrist and checkers, if not ‘gettable’ at this time of year.

THATCH – THAT CH – CH = little church, and THAT one = over there.
