In case you missed Gnarls Barkley on Top of the Pops, Gordon, the performance is archived on YouTube or more conveniently on the Matsuli blog that our correspondent Bedward has introduced us to:
http://matsuli.blogspot.com/ really is a wonderful archive
I'm afraid I did miss Top Of The Pops (as I have done for the last 20 years or so) and I did miss your posting about Matsuli. Until now. Belated thanks to Charlie and Bedward for bringing my attention to this site. Quite apart from Gnarls Barkley, it has lots of interesting stuff. Now added to my 'Favourites' list.
