I'm still trying to cold-solve enough to get going. I have about half.
So 27a, (see posts 25 and 27) I have a word for poet's agony, (specifically Tennyson in Chambers). Second letter is C. But cannot see the 'entertainment'.
Apart from that one, some that I have tried for ages are 28a, 9d, 23d. A steer on those would be great. For starters!
