This is a dark and epic François de Roubaix instrumental from the 1968 Robert Enrico film Tante Zita. A film with death as its central theme - ah French films, never afraid to tackle the BIG themes!
I used to play this quite a lot at our sister night Tonight We Fly. It is so terribly melancholy, but in a beautifully fragile and uplifting way.
[you can buy this re-issued on the monumental Disques Motors 3-disc boxset]
I have to say, based on all I've read about the film, I wasn't expecting the trailer to be quite so upbeat...
