Apparently ITV used to show this excellent music vid to fill schedule gaps in the early 1980s.
It's La Serenissima by Rondò Veneziano, an Italian chamber orchestra, specializing in Baroque music.
I don't know the recording date but it's likely 8384.

* This music was also used as title music for BBC1's Hospital Watch.

From an old VHS SP tape.
