Most of this is pretty straightforward, but, although 2 is obvious it isn't verified in Chambers (or if it is, it's not where you'd expect to find it). I lack 22 and any understanding of A and its variations. D, as well as being a well-known phrase is also a recent musical work, but none of its creators has 6 letters. There is a name linking the 4 theme words: is this the one to be written below? If so it's hard to see what the title has to do with it. I lack one of the 6 initial letters from the redundant words, and even having 5 of them shows no clear way forward.
