Cover art for Free World lyrics by Kirsty MacColl

I'm not sure it's about "Thatcherite Britain"; I always get the impression that it's about a member of the IRA which the singer sympathises with, but is loathe to condemn.

Lines like:

"If I wore your shades could I share your point of view?" - members of the IRA used to wear singlasses durng various ceremonies.

"And I'll see you baby when the clans rise again Women and men united by a struggle" - harking back to the early days of the conflict in Ireland.

"With a pocketful of plastic" - plastic explosive?

Anyway, this is my interpretation.

@geoffos42 Kirsty MacColl herself said it was about Thatcherite Britain so that one is pretty much a lock.
