Hi Tony, down here in Oz we have similar behaviour where some of the singers engage in their own vocal gymnastics, (usually the latest pop star)and find it very difficult to sing Our Anthem straight as written. This makes it impossible for anyone who wishes to sing The Anthem along with them as the phrasing is not consistent with how it was written.
Also this weekend we celebrate Australia Day which every year brings out those who want to change our flag. Not this guy.
Gary, your clip says it all. If that doesn't fill you with pride and bring tears to your eyes nothing will.That was sensational.
See Ya !!
