I actually managed to avoid trouble at Ninian Park, probably something to do with going there in the old mans car and being in the seats.I did go to a Wales v England home international at Ninian Park in the 1970s though. I was standing up then and kept a low profile.Ken Bailey, Englands self appointed mascot who used to turn up at what seemed like every international sporting event dressed as John Bull marched round the pitch at half time. Those who remember will recall he used have a big cardboard shield with the cross of St George on it. He was pelted with huindreds of beer cans and other assorted objects on all sides, and just carried on round holding his shield in the air and maintaining that gormless grin that he had. As I say, the eccentric old sod seemed to be at everything, that unfortunately included the Erica Roe rugby match.
IIRC Erika Roe appeared in the Villa programme modeling the kit at some point shortly after her 5 minutes of fame.
