Daffydog: thanks for your clue for 54 - the lack of apostrophes is my only ecuse for missing that one.
Haeremai18: The solution to 25 is a solo passage such as might be played near the end of a concerto movement. C(irca) + (a port in Yemen near entrance to Red Sea, not P. Said in Egypt on the Med) + Zuid Afrika plate (see Dutch influence!)
wallerbilk: thanks for the clue for 71 - I never thought of it as a musical, more a parody of a soap opera. 87: Handel was too much of a snob to write in this form, so he copied the Opera Seria format. This is the comic counterpart O***a B***a. It's hardly what we would call classic comedy, more that it doesn't take itself too seriously.
