So far we've had 3 eps each from 1991 & 1992, 2 from 1996, 97 and 98 and none from any other year. Does anyone actually have a copy of the 1993-96 era graphics, and would be it easy or hard to obscure (or cut) the Twix graphics? I only have vague memories of the graphics myself, having not seen them for nearly 11 years. From the 1992 era, they just blur the Pepe logo, and they cut off half the titles and the break stings to remove the Twix logos from the 1996 editions. The Chart Show was quite unique in having the sponsorship as actually part of the titles, apart from the ITV Weather, I can't think of any other show where this has been the case.
I can also remember the day of the 1996 relaunch. I gues it was quite a shock, as it was very different from any of the show's other graphics. And they retired the Amiga! Though, to be fair, it was looking dated long before 1996.
