(Apologies for being later than usual with this blog – partly because the online version of the puzzle came much later than usual, thus conflicting with the other to-dos I had today, and partly the ensuing battle with the puzzle.) I see that I missed Magwitch’s debut on a Tuesday last month. Perhaps just as well, because I struggled with this one after putting in the easy answers. The NE corner was the last to be filled, and, with no cheat button, I had to seek external aid – for which I’m grateful – for the last one. Thanks to Magwitch for, to me, a different kind of Tuesday blogging experience. Definitions are underlined in the clues.

Thanks scchua. I parsed 21a as you did, except it’s REACH minus its first letter, which is a rather unusual interpretation of “almost”.
Thanks Andrew, blog corrected – I must have subconsciously recalled the usual interpretation.
The toughest of all today’s cryptics. Thanks to Magwitch and scchua. I liked 6d originally but now I can’t get the song out of my head so I have gone off it a bit !!
Thanks Magwitch for the puzzle and scchua for the blog.
7dn: I took this as OR plus homophone of FAN(dango).
Thanks scchua and Magwith.
I had WEAN as an anagram, with “abandon” as the anagrind.
I also parsed CLICHE differently – with = c and h = honour.
Now I’m not sure about either.
Thanks for the blog and the comments. I really admire what the bloggers do.
As a relatively new setter it is helpful to get feedback on level of difficulty. Colin (the crossword editor for those who don’t know) has already asked me to think about making future offerings less difficult!
On 1ac I had in mind “plan” rather than “play” as a synonym of “programme” but I think that “play” works just as well.
I had intended Pelham Barton’s explanation of 7dn.
Best wishes to you all
Magp (aka Magwitch)
Magp @6: Thanks for dropping in. I cannot now remember whether I thought of PLA(n) or PLA(y) when solving 1ac: as you say, it works with either.
Muffyword @5: I like your parsing of WEAN: I was struggling with the same double definition as scchua had, but it does not quite work for me. I also had CLICHE the same way as scchua, and still prefer that.
Delighted that you popped in, Magwitch. I didn’t complete, but that’s because we haven’t had time yet to parse your brain circuits. Please don’t follow Colin’s advice just yet — we’ll get used to you.
