[mercedita]

Well, I slept on these 3, but still no joy. Nobody else seems to have had trouble with them. Please can someone help:
23A Piece from opera company including biblical stories (5) MYTHS? but why?
25A What 7 could be (4,5). I have 7 as MEGALOMANIAC, so COME APART? How would that parse?
Lastly, 18D How is one "high" integer over 1000? (8) I have G _ E & nothing else.

[Captain2]

23a Motet
18d Greeting (Integer + G = thousand)

[Captain2]

Company = MET + OT = Biblical stories

[Captain2]

Sorry Opera Company = MET

[Captain2]

25a What letters do you have in place?

[mercedita]

Thanks, Captain2. Fiendish!
The letters I have for 25A: C _ M _ , A _ A _ _ _ . I'm pretty sure these are right. Hope you can help.

[roslyn251254]

come again

[mercedita]

Could be COME AGAIN, AWASH, ABACK. But what that's got to do with MEGALOMANIAC beats me.

[Neveracrossword]

25 Come Again (what, eh?) - anagram of egomaniac.

[roslyn251254]

come again = anagram of 7a egomaniac

[mercedita]

just put in GREETING, which gives me A _ A _ N

[Captain2]

If 7a is 'Egomaniac' (9 letters) how did you get 'Megalomaniac' (12 letters) to fit? ;0)

[mercedita]

Thanks Neveracrossword & Roslyn! Thanks for jumping in. I didn't spot the anagram. Thanks too to Captain2. All help much appreciated. :-)
