Well, not quite branded as such, but Zeppelin fans attending the gig on Wednesday have to wear a non-removeable armband until the show.

THIS IS MADNESS!

So, this poses two questions:

1. Why do we still not have touting laws? Or if we do, why aren't they being enforced?
and
2. Would you allow yourself to be tagged like a criminal just to attend a gig?
