Only Boys Aloud finished third in the Britain's Got Talent competition in May 2012 and released their debut album in November 2012.

According to Rhys-Evans, he intended to use this one-time event to gauge the level of interest in a Welsh boys' choir.

[5] Only Boys Aloud have appeared at many events, including at the Millennium Stadium, Cardiff with Dame Shirley Bassey and Catherine Zeta-Jones in the "Ryder Cup Welcome to Wales" concert.

[1] According to Wales Online, Only Boys Aloud "won over the nation when they took third place on ITV's Britain's Got Talent".

[8][9] "Calon Lân" went into the number one position on the iTunes classical singles chart[citation needed] and the choir developed a list of TV and radio credits, including This Morning, Songs of Praise, Who Wants To Be A Millionaire: Christmas Special, All Star Christmas Presents, and Stepping Out with Katherine Jenkins.
