MOO kicks off the week…
I struggled with some of the parsing today, and I’m still not sure about 17d. (see comment by Moo@3)
However, some great clues, especially 21a.

Couldn’t parse 1a. Didn’t know “exercise” could mean “worry”.
Also have no idea where the RATE comes from in 17d.
EXONERATE
I was checking out ERAT if it meant ‘that’s’. No luck there.
Oh dear. 17d should read ‘Old English judge …’. Apologies.
Thanks for clarifying Moo@3
I was also baffled by 17d, although with the def and crossers it shouldn’t have caused too many wrong answers at least.
Very enjoyable, with the NE distinctly more difficult I thought. It did, however, contain my favourite clue: BEANBAG
Thanks Moo and Teacow.
Spent some time trying to fit “leg” for “on” in 17d, before the unparseable EXONERATE became the only option. Otherwise thanks to Moo for some delightful clues: I particularly liked 1d.
Thanks for the blog, many fine clues with neat little ideas.
Thanks to Moo@3 for EXONERATE, these things are bound to happen sometimes.
17d, as corrected by Moo@3, is a very good clue. I was so exercised by my failure to parse it that with expedition I grabbed my corkscrew, opened a bottle of Chardonnay and plonked onto my beanbag to read the blog. Having been exonerated by Moo@3 for my failure, I feel less of an imbecile.
I also liked 1a EXCISE (the surface nicely hides the definition), and Amoeba@5’s favourite, 11a BEANBAG.
Thanks Moo and Teacow for the puzzle and blog.
