Dear God, is that really what you think about us Brits at football?! Yes, a tiny minority of people sometimes have a 'tear-up' with each other on match days (usually well away from the stadium and 'non-combatants'). This normally involves lots of finger pointing, vulgar gestures, shouting, and a few punches and kicks being traded. Meanwhile, on the streets of any US City, the gangs have guns...
I go to football regularly (at Plymouth Argyle) as does Robin Dransfield, The Lakeman Brothers and Vic Legg. Perhaps we should start a "firm" of hardcore English ballad performers...
