Potentially lost series 4 audio (animated series)

I actually made a post about this in the Lost Media Wiki, but it was taken down immediately after posting because it "wasn't professional enough", so I'll abridge my post here.

I'm in search of some potentially lost audio recordings that would have been used for the fourth season of The Ricky Gervais Show if it were made. In case you don't know, the show used real podcast recordings of the titular Ricky Gervais, alongside his friends Stephen Merchant and Karl Pilkington. It ran from 2010 to 2012 for three seasons. Here's why I'm writing this post; according to the show's Wikipedia article, there was actually supposed to be a fourth season that would have used "newly recorded audio", but I have several questions regarding it. Was this audio scripted? Was it another podcast? Was it even recorded in the first place? I'd really love to hear some "new" recordings from the three of them, especially in times like these when they haven't been active together for almost a decade.

If anyone knows anyone who may have had involvement in the show, or you're just another megafan like me, feel free to help me out!
