Bomb the Ban

From Wikipedia. Sort of.

We saw a group of fancy dress hippies today but they didn't quite look the part. 

Crikey I've added a link to the word "hippies" just in case.

But their clothes weren't quite right, they weren't quite right and there wasn't a hint of that round-shouldered scraggy look I still remember so well. The main giveaway was their CND flag. 

It was upside down.
