This is a scene from 1986 blockbuster Armour of God. In these collage of videos Chan and his compagnions travel from Paris, France to the former Yuguslavia, Slovenia in order to save a kidnapped friend and retrieve the 'Armour of God'. I very much like the song, but do not really know what they're singing about as I don't speak any Cantonese. So if you have the translation of the lyrics, let me know so that I can add it as a subtitle. There is an english version though that gives an impression of the song.
