Thanks again Mark, I think there may be something else connected to that part of the chamber that shouldnt be there.

I saw Roger Waters a few years ago in Manchester, was an excellent concert!
The lyrics are really well crafted and say a lot about the things that need changing in our society. Particularly The Wall, I listened to this album a lot when I was about 16 but didnt really get it, just liked the general vibe of it. Listening to it now it means so much more, in fact and I might sit down and watch it this weekend!

Cheers, Al
