Discovery Channel Ident / Theme / Promo / Intro / Start

This can't be from 1991, as the announcer says the date is Saturday the 7th of October. October 7 was a Monday in 1991, but a Saturday in both 1989 and 1995, which means it was most likely recorded on one of these dates.

I would personally guess 1989, as I believe the ident was rejigged later on. That would mean this was recorded a few months after Discovery Europe first launched. I would love it if you could provide further information to date this clip.
