Mark Kermode - The Soundtrack of My Life
Mark Kermode is a BBC film critic. Local Hero is one of his favourite films, so he is clearly a discerning chap! Recently he has had a four part series on BBC Radio 2 on Wednesday evenings called "The Soundtrack of My Life" in which he has talked about film soundtracks.
The whole series has been very interesting but I thought I would refer you to programme 3 (I am fairly sure it's the third one) in which he talks about the Local Hero soundtrack. He also speaks to Bill Forsyth and Mark Knopfler. Don't get me wrong, the whole thing is maybe 5-10 minutes of the show, but the whole thing is interesting anyway but for a Local Hero fan that part is indispensable. For example is mentions in passing that (as has been asked here somewhere) Victor's song is actually not some traditional song, but an original composition by Mark Knopfler!
Anyway, worth checking out if you can get BBC IPlayer radio or similar.
