I never got to see this episode when I was growing up as I'm sure they didn't air it on Scottish TV. This was largely down to a bus crash into a low bridge that involved a group of Girl Guides and their leaders from Drumchapel in September 1994. A friend of mine died that day and, after watching this several years later, this still haunts me!
A bunch of loonies learned their lesson the hard way, not the brightest idea, and could have been more polite or so, and they wouldn't have crashed under the bridge.
When football is referred to as a game for yobs around 2.00, it's interesting John Alford, who sticks up for the game, became a football hooligan in series 13 of Grange Hill.
As you saw, much bigger than anything the Old Bill has in their fleet so forming a roadblock would be pointless, unless you used either vans or a couple of tanks!
