Formed in January 2000, Only Men Aloud! set out to inject some new blood into the Welsh male choir tradition by encouraging young men to sing in Wales’ most famous musical tradition. Highlights of performance have included regular slots on BBC’s Radio 4 and Radio 2, plus BBC’s Songs of Praise. In 2003 OMA! won the male choir category in the inaugural year of S4C’s Cor Cymru. In 2004 the choir were chosen to perform on three separate occasions during the opening of the Wales Millennium Centre.

They performed in the Opening Ceremony, Royal gala, and also sang in the pre opening banquet, honouring various eminent Welsh figures including, amongst others, Bryn Terfel, Sian Phillips and Shirley Bassey. This was the first official musical performance by any group in this new national venue.
