Thanks everyone.
Turast, are you sure that the adjective for 21d is french, because I thought thaqt french would fit more appropriately with 38d i.e. french fries
Also, what did you get for:
10d Colour of Phosphorus, perhaps, in Ian's gutters (7)
12d Pass prunes or any small things (7)
32d In poems, celebrate elevation of emperors (6)?O????
I thought 47ac might be (definition) sea-fox, but seem to have two Es (34d&45d)
Any ideas?
