JLS performed 'The Club Is Alive' on stage at Capital FM's Jingle Bell Ball 2012.
The track was the lead single to be taken from their second album, 'Outta This World' and samples the title song from cult movie 'The Sound of Music', something which was given the seal of approval by Julie Andrews, star of the original 1965 film.
