Former players and celebrities will also lend their support as the choirs take on a series of competitive challenges, culminating in a performance by all four before Wales v England at the Millennium Stadium in March 2007. Gareth Jenkins, Wales's new coach, believes that rugby and traditional, stirring anthems go hand in hand and has welcomed the announcement of the new series.
"Players look for encouragement from all directions and there's no doubt that the musical efforts of fans on the terraces have inspired great wins over the years," said Gareth Jenkins. "As I take up my exciting post I'm delighted to see a new, high-profile series put the focus firmly on the Welsh rugby community and the vital role that fans can play."
Dr. Stephen Mellalieu, a lecturer in sport and exercise psychology at Swansea University's School of Human Sciences, and an ex-rugby player, also says that singing can play an important role in sport; "Although there haven't been any specific studies of singing in rugby matches there's no doubt that the more it feels like your home turf, the more the crowd sings your songs, the more likely it is that the home team feels relaxed and the visitors feel anxious."
Ceri Sherlock, S4C's Commissioning Editor Music, adds; "This is a great opportunity for us to reinvigorate singing on the terraces, in the form of traditional hymns and arias in four-part voices. Although we're searching for harmony, we'll be hoping that healthy rivalry between the regions will encourage choirs to go that extra melodious mile."
The producers of Codi Canu, Alfresco, are holding open days throughout June for interested parties. No previous experience is necessary, but potential choir members must be aged 18 and over to take part. Both Welsh and non Welsh speakers, individuals and groups of friends are welcome.
