... A case where Barry's music really carries the story.
Agreed: the Goldfinger documentary explains how difficult it was to film this sequence and, in the film, the sequence does lack realism. But the music score carries the scenes, merging the militaristic aspect with the film's theme tune.
On the soundtrack it works when heard in sequence ... I'm less inclined to choose this piece as a stand-alone listen. I recall that when I compiled cassette tapes of film music or John Barry music, back in the dark ages this was not a first choice ... if ever chosen! Hence, the other two recordings you mention, Nic Raine (COPP) and Roland Shaw, whilst welcome, don't come top of my listening choices.
I always found this track to be a bit overblown and irritating. As I recall, the Roland Shaw version is less bombastic and therefore a better listen. I don`t think the impact of the scene in the film would be worse with Shaw`s more subdues version.
I much more prefer Barry`s "The Arrival of the Bomb and Count Down".
