Manitas,
The song " On The One Road" does end with " singing the soldier's song" I don't know what is sung at rugby matches.
When we were ever asked to sing the Soldier's Song in a pub we refused, unless it was the last number played. An anthem " (any anthem) is more than a song, it should be held in higher esteem than just another song, that is why we would not sing in it the middle of a show, According to etiquette is is also a sign of disrespect to applaud an anthem. At the end of an anthem there should be just silence, I get annoyed at hearing applause at most sporting events before an anthem is even finished. I also feel that an anthem should also be sung with respect, and not changed to a pop/lazz/blues/rap or whatever the singer wants, otherwise it is being treated just like a song and it should be held in higher esteem than that, Does this makes sense or am I just rambling without being clear about what I mean. ?
