I've posted before on young people carrying blades. In my youth a large minority of boys over primary school age carried blades. Every toyshop sold them, every newsagents had a "Richards of Sheffield" display of knives on a large card in the window. The difference is we weren't carrying them for the reasons they're carried now.
So there's a big (and not unmerited) flap about blades at the moment.
The kids are next door watching 'the X-factor'. Cheery Bath rugby chappie Matt Stevens is wowing them. His stage persona is remarkably like that of George Melly. What's he singing again ?
"Just a jack knife has Macheath dear,
And he keeps it out of sight.
When that shark bites with his teeth, dear,
Scarlet billows begin to spread,
Fancy gloves though has Macheath dear,
So there's never, never a trace of red.
On the sidewalk, one Sunday morning,
Lies a body, oozin' life,
Someone's sneaking 'round the corner,
Could that someone be Mack the Knife."
And the audience are loving it.
