The songs that the regions have chosen are:
Blues Choir - Delilah
Ospreys Choir - Cwm Rhondda
Dragon Choir - Calon Lan
Scarlets Choir - Yma O Hyd
Every pre-order received will count towards the single's chart position when The Official Chart is announced on BBC Radio 1 on Sunday 8th February, which coincides with the start of Wales's defence of their 6 nations crown away to Scotland.
The challenge is set to see which region can reach the highest position in the UK Top 40!
We want all Blues fans back their choir and help them race up the chart and see how high we can get. The Blues choir will be preforming live at the Winter Wonderland event being held by Cardiff Blues on Tuesday 30th December 2008 starting at 12:20pm.
The overall aim of the project is to get all four region's songs into the Official UK Chart for the start of the Six Nations tournament, which will demand airplay on BBC Radio 1 and 2 as well as national commercial radio stations.
