I can't fathom out though why Grampian kept on using the ident music for the best part of a decade. 

I'm sure they used their own ITV ident well into the mid 90s as well.

The ident music of course (which though unusual, was very nice) was kept on by a number of regions - aside from Grampian, LWT, Tyne Tees, and Border used either the original version or rearrangements well into the 1990s.

The ITV National Weather also used it, first the original version, and then a series of weather themed rearrangements (the so called “Weathergens” because Powergen were the sponsor at the time) that continued well into the 1990s till they were replaced with a second set of Weathergens with different music.

Edit: the name “Weathergens” may have strictly speaking referred only to the second set, that didn’t feature the 1989 music. Powergen was the sponsor throughout this time though.
