Thank you for a superb collection of clues, which I have to say are becoming more inspired by the week, but which make selecting a winner very difficult. I particularly liked samak's lateral effort, and ixion's witty and topical entry, which just fell short because of the disconnect between a singular noun (circulation) and plural verb (are). Harsh, I know, but fair. Eventually I plumped for sudokulover's quick-off-the-mark bad actors. Congratulations!
I don't know if you're musically inclined, sudokulover, but your prize is a way to pass the time whilst waiting for requests for help on the crossword forum:
