Schism!

Great drama in the Jed pipe band. Half the band want to play modern tunes, the other half don't. Toys are duly thrown out of the pram, and we now have two pipe bands each with approximately half the number of players.

Anyway, it's handba' day in Jed. Shop windows are boarded up and two teams of boys of all ages go haring after a wee leather ball with an aim to smuggling it past the other team and getting it to a strategic destination that will mean nothing to you if you don't live here.

To the casual observer, the game looks like a bunch of folk milling around. Occasionally this happens...

and everyone goes galloping off after the ball with little regard for their wellbeing. Hence the shutters on the windows.
