I found a little piece of paper having to do with The Circus Tour (some kind of agreement) a while ago; it was signed on 21 November 2008 by all Take That members and the signatures are by far the most interesting part of it. So here they are !
Btw: the agreement took effect on 25 November 2008 and I believe it was signed in London.
Edit: just as a reminder - those signatures are from a public document which everyone does have access to. They were on the internet already before I even knew this document (which is completely harmless btw) exists and I am just summarising what is already available elsewhere. It could well be that there are people out there who are looking for these things for fraud purposes; however, they probably do have their strategies how to get hold of a certain signature anyway and I believe that this blog post does not encourage fraud. Please feel free to comment/get in touch for further feedback. Thanks.
