I'd say the clues are slightly harder than usual, swannie - especially the thematic ones - but as the setter has been so generous with the theme and the layout, we can hardly complain. Lots of variety in the clues too, I think.
Because this puzzle is solved in true crossword fashion (getting help from crossing letters along the way) the clues can stand being tougher. When a lot of cold-solving is needed the clues tend to be on the easy side (I think).
I share your reservations about the Listener before last, and I think you were wise to leave it alone.
