I enjoyed this a lot and got on without any help, although I'm still not sure of 6d as a hyphenated form. Covering up European cuts in Guardian's leader. E?L -?P?I?G. I don't know if the second letter should be E or L and have no idea what the European cuts are -- anguilles? -- or any of it. I'm also stymted by the spoonerism of 17d, and the origin of all letters other than K and N in 18d.i loved 1ac and 9 and 11.. Very amusing puzzle!
