period of 25 years, from 1875 to 1900, most towns and villages in South Wales were represented by at least one team, though it would take until the 1930s for the North of Wales to set up their own leagues. Although difficult to prove popularity, two events that took place early in the history of Welsh rugby illustrate its growing influence on the people of Wales. The first was the Gould Affair, when a testimonial fund was set up for Welsh international Arthur Gould, instigated by a local newspaper. From an initial fund of one shilling the public response saw the amount reach into hundreds of pounds, mainly from working-class families with little spare money. The second incident was during the Tonypandy Riot of 1910, when the striking coalminers attacked the shops and premises in the town centre. 80 police officers and 500 civilians were injured and one person died. Over 60 establishments were attacked and looted, with only two buildings avoiding damage. One was a jewelers which had roller shutters, the other was the chemist shop owned by Willie Llewellyn, which despite the chaos of the events was spared due to his services to Wales on the playing field. For the match against Scotland in 2005, 40,000 Welsh people went to Edinburgh to watch the game. Over 10,000 gathered on "Henson Hill" to watch a big screen of Wales v. Ireland that gave Wales its first Grand Slam since 1978. The result was greeted well amongst fans and was even used to explain a sudden economic surge. Since 2013, the Millennium Stadium hosts the Judgement Day, a double-header fixture of the four Pro12 teams. The first two editions had over 30,000 spectators. The 2015 edition had 52,762 spectators, the highest in the history of the league. The choral tradition of Wales manifests itself at rugby games in singing. Popular songs among the fans are 'Delilah' by Tom Jones, 'Cwm Rhondda' and 'Calon Lan' and in part replace the normal chanting of other Rugby supporters. Statistics According to WR, Wales has 239 rugby union clubs; 2321 referees; 28,702 pre-teen male players; 21,371 teen male players; 19,000 senior male players (total male players 69,073) as well as 1,000 teen female players; 1,056 senior female players (total female players 2,056). Demographics Whereas rugby in England fractured into the two separate sports of rugby union and rugby league over the issue of money,
