[Blob] Depends on whether you include H, which is German for what we call B.

[rab] A likely story !

Anyway I haven't set one for a while - this one would probably spread over two answers if you know what I mean, as it is 19 letters long, and the max is usually 15 - but we don't have that constraint here.

They come in light, they punish harm - I embraced destruction ! (8,3,8)

[Blob] Rab is quite right, H *is* used in Germany (and some other European countries).

[Darren, rab] duhh ? So if H = B, what equals A (second time round ?) - or is it A,H,C,D,E,F,G ?

Germans use eight letters. The British "natural" notes A to G are represented as you so very rightly say above. B is reserved for B-flat. Apparantly it has something to do with a superstition revolving around the use of the letter B. However I suspect it is more likely due to the prevailing mode of the time. (And yes, I do mean mode).

So it's A,B,H,C,D,E,F,G ... how sensible is that ? Anyway, I don't think a Xwd compiler who used "note" to mean the letter H would be very popular with his subscribers somehow.

I guess it is Seraphim and Cherubim ? Being an anagram of "punish harm I embraced".

[Bb] It is indeed - I don't think you really had to ask did you - it was unlikely to be an anagram by accident ! I was actually thinking of them the other way round (simply coz. that's the way they are more usually said) but there is nothing in the clue to suuggest the order, so spot on, and *** for getting it so quickly - I thought as anagrams go it was quite tricky - but I seem to remember from the Cryptic Stations games that you have an aptitude for them. wd.

[Blob] Thanks, once I spotted cherub (more by accident), it fell into place. If I can get my brain in gear, I'd supply a clue. I seem to have lost touch with cryptics just lately. Haven't done a crossword in months.

Is everyone ignoring my last clue on purpose??

[Darren] I don't think so. I've just looked it up.
Punctuation, endlessly one group (9)

That'll be COMMUNITY = COMM(A) + UNITY or I'll pawn my shawl.

OK, time for another rude one folks.

Flatulence might raise the temperature when receiving head from call-girl -- coat! (11)

More a windcheater methinks - (explanation : Flautlence = wind, raise temp = heater, receiving head (first letter) of call girl = C, inserted wind-c-heater)

That was quick. Too easy, clearly...

[Blob] It's MACHIAVELLIAN (MAN surrounding A CHILLI, all surrounding AVE).

[Raak] Are you refereing to Io, a moon of Jupiter?

[Darren] It sure is - well done. I presume the pod rather gave it away, but I couldn't think of a reasonable alternative.
I'm beginning to wonder if the use of <font="white"> is really necessary - coz. once they're solved we're moving onto the next one. What does everyone think ?
