Finally caught this year's Oscar winner for Best Original Score, Atonement. There's a memorable bar scene with British soldiers belting out "Bless 'Em All," led by uke player Paul Harper.
"Paul, who plays a sergeant in the British Expeditionary Force, said that Joe Wright, the director of the film was impressed with how much he knew about the 1940s and even asked him for his advice on what song the cast should sing in the cinema scene.
"Paul said: "He came up to me and asked me if I'd like to have a singing part in the scene set in a French bar. When I accepted, he asked me what song I thought we should all sing.Link
"I suggested Bless Them All, but not the normal version - the army version which is a lot ruder! Joe Wright agreed and then I was miked-up and put on set."
