I assume it’s a copy and paste error that’s not been corrected in a template. Shit happens, especially when there’s a lot of content to get through. (I once started a list of RD DVD mistakes and had to stop – it was just depressing.) Is there another show with those stats?
I am admittedly still bitter that the Mark Lewisohn material based on his Radio Times Guide to Comedy was pulled from the BBC Comedy website, presumably because they didn’t want to pay for the licence to use it any more (possibly related to the across the board BBC budget cuts). I didn’t always agree with his opinions, but my God it was some of the best researched stuff on comedy ever, and my first choice to turn to when I wanted to check something (or link to a show on here, in case people wanted to read up on something further).
Not only do I have to use the book now, which isn’t kept up to date like the website was, but it broke about a million links across the internet, including shitloads of links on Wikipedia. The replacement stuff isn’t even remotely in the same ballpark, and covers pretty much nothing compared to Lewishon.
