Stuck on last two:
52a "Old caterer and a jazz fan associated with US" (7)
A?A?O?R
43a "With cutlery, pare outer part of joint" (10)
S?L?E?S?I? Looks like it ought to be SILVERSIDE for the joint but, unless I've got 32d (ACADEMIC DRESS) wrong, could it be SILVERSKIN or SILVERSHIN?
Any help much appreciated
