Also, speaking of EastEnders credits, I just came across this on YouTube-
Clean end credit sequences. This one from 1989:
I notice the drums at the start play over a black screen at this point, we saw some 1985/86 episodes on Drama where they cut to the credits it bit too soon (including on episode 1) and they played over a static shot of the map (starting to move once the music starts).
This one is from 1991 (after they cut the length down). Interestingly from the short period they introduced a new arangement of the theme tune (sounds quite similar to the 1994 version), before changing back to the original
Here from 1992 (after going back to the original):
I think having the copyright date burned in was the reason why EE kept the old BBC logo until the end of 1997, they didn't want to re-edit it for a few month's use.
They re-did the opening titles in 1990 as well, by doing what looks like rescanning the original film- so the quality's a bit higher, and you see a bit more of the map in the end shot, and using an electronically generated EastEnders caption, rather than the optical film caption of the 1985 titles.
