 A phenomenon of Welsh industrial communities was the appearance of male voice choirs , believed to have been formed from glee clubs . The Rhondda produced several choirs of note , including the Rhondda Glee Society , who represented Wales at the World Fair eisteddfod . The rival Treorchy Male Voice Choir also enjoyed considerable success at eisteddfodau and in 1895 sang before Queen Victoria . Many choirs still exist today including the Cambrian Male voice choir , situated in Tonypandy .
