This is a toughie! Despite all the help on this site (for which many thanks to all) I still cannot finish this puzzle. I have ideas for solving most of the outstanding clues and I would be extremely grateful if some kind person could tell me whether I am on the right lines. I am not really looking for specific answers: I do not think that would be in the spirit of this forum.
I am afraid it is rather a long list and if nobody feels like responding I will fully understand.
1 across: I gather that the answer is ACE + a synonym for summons + S with N inserted somewhere.
9 across: not sure whether to omit IN or IS: I assume that SNACK is the definition and that the answer ends with E.
11 across: I gather that ASIAN MUSIC is the definition: MUSICIANS must therefore be deleted: stuck after that.
13 across: MIT must be omitted, but that is as far as I have got with this one.
20 across: I get LOLLS, but this has too many letters: I think it must be LOLS
23 across: I think ROYAL is the definition and I need a synonym for TOOK IN in ZA with L inserted somewhere
25 across: IOWA is omitted and I think TURTLE must be the definition, but that is all I have got.
27 across: O`FLAHERTY omitted: triple definition.
30 across: CENTIMETRE omitted, then a word for crack containing two L`s with one of them omitted.
33 across: not sure whether to omit AWARE or AFFECTING: I assume the answer ends with L.
44 across: ADVERTISE to be omitted, but that is all I have got.
1 down: I assume that FISH is the definition and the answer is S + a synonym of BATTERED.
4 down: not sure whether to omit TITANS or TRACKS, but that is all I have got.
7 down: ENDS omitted: I gather that DEFECT IN US is the definition and the answer is a synonym for REP in a synonym for HOSTILE WORDS.
28 down: ECSTATIC to be omitted, but that is all I have got.
