This puzzle was inspired by Lemonade Disco which is an American website that commisions a set of puzzles each month, all loosely based on a similar theme idea. I submitted a version of this puzzle to them but didn't really expect them to use it. I have tweaked the puzzle slightly and uploaded it to mycrossword.co.uk. I won't say here what the theme is as you may prefer to discover that for yourself as you go along. I don't think this is one of my best puzzles but has some nice stuff in it that I'm quite proud of.
