Quite a long shot here, but I watched the GH program Driven again last night and the music has got me stumped ??? The starting images are overlaid with a slow melodic theme (a long chord played on what sounds like a Hammond organ), with intermittent guitar chords - which sound just like Gilmour. It could also be Mark Knopfler, as it has a 'Local Hero' sound about it too!
I have racked my brains to try and think what it is, there is nothing found on Google, apart from unanswered questions from other people asking the same thing - anybody have a clue, a long shot I know, but some here did see it when it was originally broadcast. If I can think of a way to get it from my HDD recorder I will convert it to MP3 and post for you to hear?
I did think of 'More' but it's not there.

GG.
PS And yes, I have checked the programme credits!
