With Wales winning the Six Nations Grand Slam last weekend, musical ears and eyes are turning to Sunday's chart rundown, to see if Cwm Rhondda/Bread Of Heaven can break into the hit parade.
Paul Child recorded the Millennium Stadium crowd singing the 1907 John Hughes hymn at half-time. It was rush-released yesterday, credited to Wales.
Watch a video as Hen Wlad Fy Nhadau rang round the stadium:
With a capacity of 74,000, the stadium held enough people to take the song into the top five if everyone bought a copy.
Half the audience purchasing the charity single would bring it to the top 10. However, twice the capacity of the stadium would be needed to almost guarantee a chart-topper.
Lauren Kreisler of the Official Charts Company said: "We wouldn't speculate as to how the song will do, but it's an interesting story. You'll have to wait till 4pm on Wednesday when we publish our midweek charts to find out how it's doing."
Paul Child told the Western Mail: "It's an idea which came about because we wanted to get as many fans involved with the single as possible and Bread Of Heaven is famously sung on the terraces and throughout the stands so what better song to choose as the Grand Slam single.
"But ultimately it's a celebration of this year's tournament. It's a way for fans to thank the team, letting them know how grateful we all are and how proud we are to get behind them."
Cwm Rhondda/Bread Of Heaven is available in physical form at Tesco stores in Wales and on download sites. All proceeds from the single will be donated to the Welsh Rugby Charitable Trust.
