Know your rights

I'm a bit of a Clash obsessive. I gave away my vinyl collection a few years back, as it was just getting mouldy and I couldn't play it. But I do have a slight regret about some of the artwork, particularly for the Sandinista booklet, and here the Combat Rock lyrics.
On another note, the lyrics to Know Your Rights seem more applicable today than they did then. Where are the angry young men writing these songs today?
The book is The Return of the Last Gang in Town by Marcus Gray.
