During July 1928, the choir were busily rehearsing for the Caerphilly and Aberdare Eisteddfodau. They did not succeed at Caerphilly and their performance at Aberdare is not recorded.

Their next competition was the Llangynidir Eisteddfod in May 1929 when they carried off premier honours consisting of a handsome cup and prize money.

In September 1929 the choir announced its intention to compete the following year at the National Eisteddfod at Llanelly. No records have been found of their performance. However, In December 1929 the conductorship was taken over by Thomas Walters A.L.C.M.

Prior to the choir’s third successive victory at the Llangynidir Eisteddfod during June 1930, many local concerts were given. The following is an extract of the Merthyr Express report dated 14 June 1930

The test piece was "Tempest and Calm," (B. Gregory Evans). The composer, who was one of the adjudicators, said it was magnificent rendering, and the conductor's conception of the piece was a correct one, for which he and his party were highly complimented. The Party were given a hearty welcome on their return home. Fog signals heralded their approach to the station, and before dispersing they sang a chorus in the Square. The accompanists were Mr. Wyndham Lawrence and Mr. J. Thomas.

This success was followed by another at the Llangattock Eisteddfod during September 1930 when they came first out of a total of six competing choirs.

During November 1933 it was decided to reorganise the choir but the outcome is not known.

In October 1932, Thomas Walters resigned as conductor and his successor was Griff Jones.
