As in clean, are you meaning what I think you are i.e a completely clean copy free of graphics and the like? If so, I think it would be very difficult to obtain a copy from the BBC and obviously impossible to find one outside the BBC.
However, if you're just after a normal show you should try the beeb - if you don't ask, you don't get! There may of course be a charge involved though.
First point of call, for clips anyway, is www.saturdaymornings.co.uk - although they don't necessarily provide any video copies of material on the site...
(I have a feeling that Martin who runs that site is here on TV Forum...somewhere...)
Also the theme tune is not all that hard to find around the web, if that's what you're after too...
Thank you to everybody that has help me on this topic. I've contacted the BBC and they are indeed now dealing with my request. I must admit, i've not seen copies of the Live and Kicking theme on the net, but if somebody could point me in the right direction or has a copy that they could upload, that would be fantastic news aswell !
I take it nobody's got the theme then? Maybe someone with the old Showmaker computer game?
I had it, and remember discovering the titles in MOV format on the disc, which would've had a good quality version of the theme. But I've since lost/binned that.
