This is my very first attempt at a meta puzzle, so I kept it fairly easy on myself. I tried to keep the clues as 'natural' as possible, which was quite tricky at times. 8A in particular took some searching. Initially, I had a clue there about Vivaldi's "The Four Seasons", but on reflection that seemed too obscure and far-fetched. Anyway, I am quite satisfied with the result. I think I'm going to stick largely to themeless puzzles and minis, but an occasional dip into a theme or meta seems quite enjoyable.
Oh, so sorry, I did indeed forget that! Let me quickly explain how the meta works. In all across clues there is a number or a reference to a number. You take the letter corresponding to that position, and if you read it from top to bottom, you get the solution to the puzzle.
