I have similar memories to other reviewers having seen the film in 1963/64 at the age of 13. What made the biggest impression on me were the opening credits which I recall being genuine footage of street fighting in Algiers which would freeze to display a credit and then move on. All to the sound of Concerto Disperato played, presumably, by Nino Rosso. Concerto Disperato is available on Nini Rosso Greatest Hits CDs. But my advice is to ignore as the Ken Thorne version is far superior a) in terms of trumpet playing and b) arrangement. Especially as Nini Rosso sings (badly) over the middle section. But getting a genuine CD recording has alluded me for years. I have a ripped mp3 (off a 45). The film overall made a big impression but I often wonder whether, if I saw it now, I would be bitterly disappointed. After all, I was only 13 when I saw it.
