St Cyres was a nightmare in my day both on or off the rugby pitch, Stanwell far less. We never played against any Cardiff school in rugby so no idea what they were like .
Bizarrely, Grangetown , Llanrumney and Ely all played in the Barry and district football league. As Llantwit were dominant in my period we handed all of them a beating on the pitch. However a Tarki led mob chased us off the Marl after we got a late winner and got a little cocky.
