On deeper investigation, the recent BBC grab and the YTV ORACLE grab are from 1992, despite the 15 September being a Saturday in 1990. Unbelievably, the headers are consistently reading the wrong date, both on the Ceefax and ORACLE grabs - the news items point to September 1992, so it's either the 5th, 12th, 19 or 26th September. It's definitely a Saturday as the TV Guide confirms this. My guess, from the news, is that it's the 5th.
I need to find older recordings to go at. I seem to remember that Ceefax was full of music reviews, puzzles, telesoftware and quizzes, and was much more magazine-like in feel; I'd love to see it again.
