At my folk club we had not one, but two school heads, plus three teachers. We're now down to only one school head and no teachers due to them all getting cheesed off and taking early retirement. On the Forces side, my nephew is a RM commando and is learning banjo - I had thought to tell him to learn a proper instrument, like a guitar, but decided this may be a bit risky in view of his training..... Not sure if they have folk clubs in Afghanistan, but when they do, he may well find he's in demand!!
