Stuck on last three
21dn A feast helps one upset about love (6) I have ?S???A Anagram of AIDSIO?
27ac What's essential to self control, perhaps in jug? (4) I have ?L?E
30ac Dilute riveting song on record (6) I have ?I?RIAL
Some of this assuming that 22dn is PTERIA (Stuff that may be seen in the theatre comes from pirate broadcast)
Thanks for any help
