sorry about the typos-it had been a long day!
The correct clue is, as NeilM said,
''Traveller's Rest'' perhaps seen to supply cups (8)
On reflection, 1d is probably Dow Jones, but for some reason it is given as just one word in the clue.
...and
thanks NeilM for IROQUOIAN, it makes sense now, and
thanks aristophanes, and sorry about your wasted effort because of my typing errors(it just took me five attempts to try and type errors!)
thanks, leon, that seems to fit, but i'm not sure about the wordplay; could you please explain it?
I'm also presuming that another of my clues - 29a Jack and bluefish perhaps taking a new heading (6)SA?L?R (with the R from stopover) - is sailor, but again I can't work out the wordplay. Any ideas?
I also have a full grid and have highlighted everything that needs to be highlighted except for the three word title, which I think is ambiguous. Can anyone who has worked this out confirm that this consists of a full entry and its clue number? This is the only way I can logically justify my answer.
unclued, 8d wordplay is topbanana(star entertainer in lineup) top banana remove letter b=anana,28d pets backwards in miss, def misssteps.hope this makes sense
thanks re diagonal hint cant see anything obvious yet
