That's got to be it. I didn't mention it in my first post but I thought the first letter might be H because the clue that runs through it is "Hint for act accepted by dramatist" and I think the answer to that one may be Shadow (do inside Shaw). But as you say about using "citer" for caller, using shadow for hint just seems a bit of a stretch.
If it was from the 80s I probably did it in crossword corner (aka "Jurassic Park") in the staff common room, but it rings no bells.
We only did the Times in the staff room, but I much prefer the Guardian.
