Being a bit of a curmudgeon here, but I've always thought of songs being of British origin in our army and the chants especially are some thing picked up from the Americans. I believe songs might have been an in thing in WW 1 & 2 and really never saw anything that was passed onto us in the army. Mind though, I remember the RCR (forget which Battalion) in 61 had some really good profane ones sung around a fire and a bottle or two of beer on exercise in Petawawa . The chant business I think is an American invention and should stay there. The German army issues a song book for their soldier to learn the various songs and they do sing them. Especially at the end of the days training on returning to barracks. I can remember in Fort Prince of Wales watching the German soldiers from barracks in Hemer behind our Fort, marching along, out lined against an evenings dusk sky line, singing their songs as they returned to the barracks. Made one pay attention and listen in admiration. My wife still has her fathers song book from his Wehrmacht days.
