Richard Williams was recognised in the 1938 National Eisteddfod for his musical talent and at the age of 15 began touring with a troupe of singers around the music halls of the United Kingdom before returning home to join the fledgling Welsh National Opera.
With a part-time job selling insurance helping to keep the family going, he devoted the rest of his time to music and formed the Gentleman Songsters in 1951, followed by the Richard Williams Singers in 1965 and the Richard Williams Junior Singers in 1966.
Each achieved remarkable success, with frequent broadcasts, recording sessions and tours of Europe and North America.
In total there were 24 overseas concert tours, performing in Moscow, Vienna, San Francisco, Los Angeles, Prague, Paris, Toronto and Vancouver.
Williams died at his home in Thomastown, Rhondda Cynon Taf, South Wales, at the age of 84.
