Why do wales sing the anthem before a rugby match?

Answer 1

The story goes that in 1905 Wales played the All Blacks and following their haka the Welsh Fans sang their anthem at which time the welsh Squad held their ground until its completion . This is is reported as the first time a national anthem was sung before a sporting event. Such was its impact 12,000 miles away from home, the All Blacks were overwhelmed by the sound that the New Zealand captain wrote later that he had never experienced anything like it in his life, and that it sent a shiver down his spine when the anthem was sung at a deafening volume
