many thanks, mrs trellis. I now see that 13a is an anagram of "on the fair" with the f missing, but sady I have no letters for 8a.
Now I shall have to resort to asking for three down clues, which will help:-
1d "Sharp right taken in coach by that Parisian"(7)
2d "Hurry to make progress"(4,5) ***E,****G
3d "Go away and bang your drum"(4,2) ***T,**
Having a bad weekend, I normally manage to finish the Saturday DT without too much trouble - senior moments !!
