Oxymoron

They say it's time to crack down on what they call obscene
But what they meant is blokes like me and the life I chose to lead
OK let's have an uproar, their troops are marching in
With determination in their eyes they've rallied all again
[chorus:]
Come on, come on
Give me a Petrol Bomb
The riot troops assembly is finally marching off
A few had luck and could escape the baton-slinging lot
Some fellows are arrested, perhaps they're locked away
You lift your bottle and set out to have your fun again
