Three Alan Moore Quiz Questions

I am making a long reach here but why not?

(i) In which two works does Alan Moore adapt the song-title, "When Johnny Comes Marching Home," in different contexts?

(ii) In which two works does Alan Moore invent different although related meanings for the letters, "N.F.," which, in British politics, stand for "National Front"?

(iii) In which two works does Alan Moore refer, in different ways, to 1984?

Clue: of these six works, five are comic strips and one is a prose novel, of which Moore has so far written only two. Because of the preponderance of comics, I have posted these questions on Comics Appreciation rather than here where I am currently discussing Moore's prose fiction.
