Tom Jones joined the pre-war Choir in 1938 with his friend John Haydn Davies. The partnership was reunited at the forefront of the Treorchy Male Choir when it was reformed in 1946 and Tom carried out the role of Accompanist for the next twenty five years.

At the National Eisteddfod, Aberystwyth, Tom gained a personal tribute from the adjudicators for his playing of the flowing accompaniment in Schubert’s setting of Psalm 23, “Glywsoch chi’r piano?” ("Did you hear the piano?") said Mr Matthew Williams.

It was the first of many accolades Tom would receive for he accompanied the choir through seven of its eight National Eisteddfod victories, all five of its Miners' Eisteddfod victories and almost every semi-national eisteddfod entry. He also appeared on many of the early commercial recordings produced by Qualiton.

His unobtrusive efficiency at the piano over the years contributed in no small measure to the success of the Choir. He and John Haydn Davies worked in complete harmony in every sense of the word. A man of few words, Tom was an unassuming person and endeared himself to audiences and choristers alike. Originally a collier, he later became an insurance agent and studied piano in his leisure time. He was a Life Member of the Treorchy Male Choir.
