The Choir was formed in 1967. While many members come from the Welsh community in and around London, it is open to anyone who shares a passion for singing and enjoying themselves. The repertoire ranges from traditional Welsh folk tunes and hymns, well known opera choruses and spirituals, to lighter numbers including pop songs and hits from musicals. The Gwalia is in demand for public concerts, cabarets, weddings and other private functions, frequently performing in Cathedrals, concert halls, churches, hotels, clubs, offices and village halls throughout the UK. The Gwalia makes recordings on radio; concert and TV appearances. The Gwalia has been a prize-winner at the Royal National Eisteddfod of Wales and the Llangollen International Eisteddfod, has performed in London's Royal Festival and Royal Albert Halls, St James’s Palace, and on the pitch at Wales' rugby stadium in Cardiff. The Choir has made concert tours to many European countries.
