What Song Is This ?

i want to know the name of the song from 0:00 to 2:15... it's a damn old song... i think it is from 1930s or 1940s... not so sure... i always love old songs... old songs are classic and nice to listen to as it can enchance your feeling... haha

ignore the video and concentrate on the song instead... this is a WW2 video which i think you guys are not interest with... so don't bother to watch it... listen to the song is enough already... i found this video when i was searching for some historical documentaries in youtube =.='

if you guys know the name of the song... pls tell me ok??
