Noddfa's last minister was a member of a prominent family of Welsh preachers who included Jubilee Young, minister of Seion, Llanelli for many years. Membership at Noddfa peaked at 713 in 1905, in the immediate aftermath of the Welsh revival. In common with many other chapels in the industrial valleys of Wales the membership declined thereafter, but was still at 398 in 1945. Significantly, however, there was a drastic fall in the Sunday school numbers after the Second World War, from 198 in 1945 to 25 by 1965. This was a symptom of both the increasing secularisation of society and the relative decline of the Welsh language, especially amongst the young. By the 1960s the Sunday school had largely ceased to function. Membership, however, remained at 208 as recently as 1970. Music Noddfa has an important role in the choral tradition of the Welsh valleys. The chapel had its own choir, conducted by John Hughes, and oratorios by Handel, Mendelssohn, Haydn, Beethoven and Mozart were performed on a regular basis, with three or four such productions each year. There was also a flourishing and successful children's choir.
