Apart from two solo dances, all those danced at Nantgarw are for four couples, whereas those we call the Fair dances were for twelve men and women in gaudy fancy dress. At this time it was still customary at country fairs to lay down a wooden floor in a roped-off enclosure, where dancers from the town or outlying villages might dance to amuse themselves and collect donations from spectators. A master of ceremonies, in semi-military dress, controlled the proceedings. Anyone might call for a particular dance they wished to see, and it was at her grandmother's request and the payment of a shilling, that little Margretta first saw 'Rali Twm Sion'. The child was pushed to the front and, resting her chin on the rope, she watched entranced while the twelve dances, in red and yellow, with bells on their dresses, caps and fingers, led round, danced heys, round again, cast out and weaved up, marched to the corners and serpentine back; all very much like a processional Morris, adapted to a confined space. Although there were both men and women, it is not really a partner dance, with bells on their fingers, they cannot take hands. One remembers that one line in a processional Morris, is usually dressed to represent women, if only in the matter of hats. It would be a slight adjustment to substitute actual women. We may possibly see in this the missing link between the traditional dance and what is known as the Fluffy Morris.

The other Fair dances are 'Ffair Cerrffili' danced, Mrs Thomas believes by Caerphilly people; the women wearing ordinary dresses of pale grey, with a woven pattern of true-lovers knots; and 'Dawns y Pelau' (the ball dance). 'Ffair Caerfilli' is not unlike 'Rali Twm Sion', but the step Mrs.Thomas describes as three running steps quickly backwards and forwards, starting always on the left foot, the right foot kicked quickly backwards and forwards. In changing directions, three jumps are made, with shoulders moving oddly in a kind of shrug. I am inclined to think that the running, carrying step, is a degenerate form of the Morris half-caper. In 'Dawns y Pelau' small tinsell balls are attached to the hands by elastic and are tossed up and out continuously during the dance. A few years ago the very balls appeared in Woolworth and a member from Abergavenny remembers playing with similar balls, years ago at school. There is no excuse for teams to appear on the Eisteddfod stage, throwing enormous beach balls.

Mrs.Thomas has now seen many attempts to revive these dances' "I have thought much about it so much" she said, "that I often feel as if I were back again sitting on Yr Hendre, or under the oak at Dyffryn Ffrwd, or at the fair with the feel of the rough rope under my chin and I see the dancers as plainly as if I were really looking at them again".
