Their next documented success was at the Pontypridd semi-National Eisteddfod during July 1927 carrying off premier honours out of a competition of 11 choirs drawn from all parts of Wales. The test pieces were, "My Love dwelt in a Northern Land," and "The Song of the Pedlar." The accompanist was Mr. Wyndham Lawrence, A.L.C.M.

Another success was reported in the 6 August 1927 edition of the Merthyr Express.

Ladies' Choir: Major Success   Enthusiastic scenes were witnessed on the return of the Ladies' Choir from Glynderwen, Carmarthen, on Monday night, where they had been successful in winning the first prize of £25 and a beautiful challenge cup out of the competition of 10 choirs. The adjudicator paid a glowing tribute to the Fochriw Choir. He said they had given a magnificent rendering, and awarded them 95 marks. A very high compliment was paid their brilliant conductor, Mr. D. J. Thomas, A.C., who had brought his choir to such a fine stage of perfection. On his return on Monday night, he was carried shoulder high amidst the cheers of his admirers. Since the formation of the choir a few years ago, they have made wonderful strides in the musical circle, having obtained several first prizes, and we predict still greater honours await them. Their singing is well worthy of National honours; we hope soon to see them - if they remain loyal to their conductor and faithful to their practices - winning still greater honours. A word of praise is due to the energetic secretary, Mr. Gwilym Thomas, who is untiring in his work; to the brilliant accompanist, Mr. Wyndham Lawrence; to Miss Thomas, president; to Mrs. W. J. Payne, chairman; Mrs. Aneurin Jones, treasurer; and an excellent committee. Also, to Mr. W. Davies, stationmaster, who is always so ready to do all in his power in the matter of train facilities for the welfare of the place.

Competition singing continued with unsuccessful performances in the Cardiff (April 1928), National at Treorchy and Clynderwen eisteddfodau (both August 1928).

In October 1928, the conductor D. J. Thomas, moved to Caerphilly and it may be that the choir disbanded since there are no reports until April 1933 when it was announced that the recently-formed Ladies Choir, under the conductorship of Madam Hannah Cole-Davies and accompanist Wyndham Lawrence were practicing for the Mountain Ash eisteddfod.

A number of successes in the following eisteddfodau were recorded, Merthyr in September 1933 (Joint first with Dowlais), Abertysswg in October 1933, Deri in November 1933,Ebbw Vale November 1933, Pentrebach November 1933, Bargoed in October 1934, Aberdare Hospital in September 1935, Aberfan in February 1936 and Aberdare in August 1936 when the choir came first in all.

The choir competed in the Liverpool Eisteddfod in April 1935 but the outcome is unknown.

The last newspaper report to hand is that in the 2 October 1937 issue of the Merthyr Express when it was announced that the choir had competed in the Abergavenny Eisteddfod but were unplaced.
