I’ll accept that 4d & 20d are “cryptic definitions”, but reluctantly. I didn’t think they were cryptic.
Why is plonk set? The no in piano eluded me. And hey, I’ve a new addition to my list of British rivers!
Overall very enjoyable, with plenty of smiles. Thanks Slormgorm & Teacow.
20a, not 20d.
Thanks, Slormgorm and Teacow!

Agree with you that the crypticity index of PENSIONERS, as well as POLICEWOMAN, is low.
KAMA SUTRA is sweetly cryptic. Liked it.
GDU@1
PLONK=set (as a verb), I think.
I couldn’t find plonk/set anywhere I looked. I suppose if you plonk something on a table, you set it on the table. A bit of a stretch though, methinks.
Yea. That is the sense I was referring to.
Kama kama kama sutra with me
In position 31 it was terrific fun
In position 72 you were me and I was you
RIP dear Viv

‘promoting’ in a down clue has an in-built 69!
Good Monday enertainment from Slormgorm. I immediately thought that ‘German tank’ in 24a was going to clue “panzer” but no such luck. I didn’t know OLD ROSE as ‘A shade’ but bunged it in as fitting the wordplay as I couldn’t face an alphabet trawl.
Highlight was the excellent cryptic def for KAMA SUTRA; Slormgorm at his best.
Thanks to Slormgorm and Teacow
Yes, I concur; KAMA SUTRA on top!
And I liked AGENT ORANGE and NUTLOAF.
Thanks to Zamorca and Teacow.
copmus@7 – I’m a fellow fan of The Bonzo Dog Doo-Dah Band – I can’t resist the urge to post this again.
Viv Stanshall(1943-1995) and Neil Innes(1944-2019) were comedy and musical genii.

Here’s a short – 41 seconds – musical interlude. Kama Sutra from the LP The Doughnut In Granny’s Greenhouse(1968)

Thanks S&T
loi PIANO – spent far too long asking myself “How is No doctor?” when it should have been “Who is Doctor No?” Doh.
Needed to consult Chambers and OED because Wiktionary has no idea about OLD ROSE as a colour, or the “Buff” colour of NANKEEN.
It does know AGENT ORANGE ‘from the orange-striped barrels in which it was shipped.’
Thanks for the blog, great puzzle, a very friendly grid, I think every answer had a crossing first letter and they are the most useful.
NANKEEN seems to be one of those words that fits in certain areas , buff is one of those words with so many meanings.
The setter needs to use less “A”s in his clues. They often serve no purpose (see 26A, 13D). Fun puzzle though.
Jay @15
Not 13D though. The first ‘a’ is part of the wordplay and the second, if removed, would change the meaning of the surface completely … unless referring to a similarly orange male stripper!
