London, Mar 14 (ANI): JLS are teaching the likes of Austin Healey, Bill Beaumont and Brian Moore to sing as the rugby stars have to perform in front of 82,000 fans at Twickenham.
The sportsmen will be singing 'Proud', JLS's official single for the charity Sports Relief, before England's final RBS 6 Nations game against Ireland.
The 23-strong group of rugby players - The Sport Relief Big Hitters - have also been receiving training from vocal coach Zoe Tyler ahead of their musical moment on the pitch.
"There have been many times in my life when I've been filled with nerves and adrenaline before a big game, but nothing compares to the terror of singing live in front of a full house at Twickenham," the Daily Star quoted Healey as saying.
Another member of the chorus, Mike Catt, hoped he wouldn't hit a "bum note" in front of the crowd.
"We've all had some practice singing in public as we've all belted out the national anthem before kick-off, but I don't think that compares to having to sing in tune for three minutes.
"The boys and I are going to give it everything we've got. I just hope we don't hit a bum note," he said.
The group will perform once again - accompanied by JLS - during the Sport Relief Night on BBC1 on Friday, March 23.
JLS's version of the song is released on Sunday to download and will be available on CD on Monday to raise cash for the charity. (ANI)
