Just winding up on this one - didn't get 5 Down, which is:-
"Couple in bar turning round, making you jump" (4) A-E-
Also, can't fully parse 46 Down "No longer nurse a lonely heart, say. if looking up old dramatist" The answer would appear to be "SENECA".
And, next to it, 47 Down, "Like soil often put in church yard primarily"
I can't accommodate the "L" in what appears to be "CLAYEY"
