10d Vigorously attack dirty old man (4)
17d Singer fellow attacked on board (5)
Sorry no letters for these as they have to be changed on entry to the grid
Single letter misprint in these clues:
8d Move past edges - nothing - I swept superlatively (7) G??I??T
12a Creep's request to Turk to stop cup match (6) TI???? .... cup match might be tie??
hankir ... you only really need the last few words of the message to solve the clue which you will need for its "partner" to highlight in the grid .....i bet you've seen it already.
