Too easy for everyone else obviously, with no thread visible (apols if I have missed it).
I'm just stuck on two, with everything else solved:
18a A lot of hard pieces for one performer (4)
I have S--I
10d Mussels served in a local before 10 (4)
I have _NI_
I would grant you my deepest thanks for any hints, I can't even find somewhere to start with them! :blush:
