All done and thoroughly enjoyable too, but for completeness would appreciate if someone could nudge me in the right direction on the parsing of the wordplay on 30, 37 and 39.
Hi candledave,
30 double definition, check Chambers ² & ¹.
37 excluding (Sabbath and holy)
39 Two = 1st 4 letters of answer (again Chambers), next 5 words of the clue define the next 3 with the usual abbreviation providing the last.
