The usual varied and entertaining puzzle from Julius, thank you.
In the grid we have Lets Go Fly a Kite from Mary Poppins:
With tuppence for paper and strings
You can have your own set of wings
With your feet on the ground
You’re a bird in a flight
With your FIST holding TIGHT
To the STRING of your kite
Oh, oh, oh!
LET’S GO FLY A KITE
UP TO the HIGHEST HEIGHT!
LET’S GO FLY A KITE and send it SOARING
Up through the ATMOSPHERE
Up where THE AIR is CLEAR
Oh, LET’S GO FLY A KITE!

I write these posts to help people get started with cryptic crosswords. If there is something here you do not understand ask a question; there are probably others wondering the same thing.
Lovely puzzle-I could see some sort of link but thanks for zooming in on it, Pee Dee and thanks Julius.
Liked the uplifting theme, even if I only recognised it post solve and couldn’t identify all the references.
SEIGNORIAL is one of those words you could use in just about any circumstances and pretend it means whatever you want as no-one is likely to have ever heard of it. I hope to be able to trot it out soon. RURALITY was also new, though not quite as appealing.
Thank you to Julius and PeeDee
I went round anti-clockwise from top left; LOI FLY A KITE, with a massive clang. I liked ATMOSPHERE, ANTIPODEAN and CLEAR THE AIR, the more so since it’s thematic. 12 blue solutions pretty impressive for a sensible grid.
Thanks Julius, PeeDee
Missed that theme completely but musicals have never been a strong subject for me, so I’m not surprised. An entertaining solve, with the SW corner last to crack.
Thanks to Julius and PeeDee
Liked this one, thanks to Julius and Peedee.
Just one niggle. Is it OK for “it” to do double duty in the parsing of 29A?
Hi Stephen – the double use of “it” was my mistake. Fixed now.
Thanks to Julius and PeeDee. Very enjoyable (though as usual I missed the theme). I took a while getting the combination of AZERI, HEIGHT, and SEIGNORIAL (my LOI).
Thank you Julius and PeeDee, this was very enjoyable. I’m glad I’m not the only one who missed the theme.
Any particular (Poppins-related?) reason for 1545? Could have been any one of Henry’s 56 years?
Thanks Julius and PeeDee
Another cracking puzzle from Julius, made all the more special with the theme that I did look for post solve, but couldn’t spot – don’t think that I have ever saw Mary Poppins. The actual solve time was quite a bit shorter than normal for this setter with the parsing of HEIGHT the only thing that I didn’t see. Talking of which, it needs to be abbreviated to HT in 11a to get the full TIGHT.
Always thought that a zephyr was a gentle breeze, whereas a gust was a more forceful one but see that they were listed as synonyms in the online Oxford.
Finished with the clever BOWYER, ATMOSPHERE (with the interesting PM fodder) and FRET AT as the last few in.
Well spotted Bruce, fixed now.
In 19 across, I took 1545 to be football halftime (HT) which contains eigh (Henry eight diminished). Maybe I’m wide of the mark.
