What did the BBC Nations do? I know Wales and NI take network coverage these days but did they opt out for celebrations in Belfast and Cardiff? Did Scotland opt out for Hogmanay? Did they put the network coverage on their respective BBC Two (like they do with election coverage) or simply not bother?
If there were any credits, how long were they?
As far as I remember, Scotland did their regular Hogmanay programmes on BBC2, Wales and NI didn't do any special programmes. Of course, Jools' Hootenanny that year was on 30th December, so it wouldn't be overshadowed.

The BBC2 shows were quite interesting, actually, the TOTP2 90s special was actually repeated the other day, and then at 10.20 you had Goodbye To The Nineties which was an absolutely brilliant compilation of archive clips from the decade arranged in an A-Z. There were no presenters or narrators but a few people popped up to add a bit of context, Laurence Llewellyn-Bowen did a bit about interior design and I remember Ally McCoist was interviewed during the football bit. I remember there were loads of clips of the Armistice in it as well. It was a great show, and they repeated it three months later. Indeed when they did I Love The Nineties eighteen months later I was probably the only person who thought it might be worth doing, based on that show, but it was nowhere near as good.
Then at 11.50 they simulcast BBC1, but one of the most interesting bits of the night was that the Fatboy Slim doc was actually ten minutes shorter than billed and so at 12.45am they showed, unscheduled, the episode of Danny Baker's TV Heroes about the Top of the Pops audience, which was a fantastic show and I desperately scrambled for a tape to record it.
Of course, ITV had Countdown 2000 during the day. This was produced by ITN from the normal news studio, though I remember they had armchairs rather than the desk, and every hour they'd pop up, including in the middle of films and other shows, to link into live pictures of midnight from somewhere, and then they stayed on from 11pm until after midnight.
2000 Today has got a bit forgotten now and I've said this before but it falls in that period between widespread VHS and the rise of digital, so I think many of the clips now only survive in obselete formats on long-abandoned websites. The comedy clips in that video up there are quite interesting, they commissioned a load of comedy sketches with a stellar cast list - including a Two Ronnies reunion - but they got a bit swamped by all the other things going on, and were then compiled into two programmes shown after ten o'clock -

The brilliant VHiStory blog has done a few posts about it including lots of grabs and clips...

The latter includes one of the most memorable bits, Jamie Theakston getting a bit emotional at five in the morning. As I mention in the comments, David Dimbleby said beforehand he was honoured to be given the role of saying the first words of the millennium and had been spending a lot of time thinking about he might say. And in the end he said, er, "Well, it is now the year 2000".
There were no credits, because I remember waiting for them at the end and there weren't any. Of course, when it was announced it was reported Des Lynam and Jill Dando would be doing it, but by the time we got there neither were available, for very different reasons.
