Finished crossword other than bottom left hand corner. Brain has now given up.
16d Unhappy climbing over a church and country houses (6) D?????
19a In these cafes, initial cost of charges jumps (6,5) ??F?E?,S?O?S (Looks like buffet something?)
23a Not giving in corrupted data, chap's arrested (7) ??A?A?T
26a Goes into a dive to get good seats (6) ?T?L?S (Looks like stalls but I can't get the wordplay)
Any help much appreciated to finally put this one to bed (or in the bin!) Thank you.
