Have you seen the film version, Guest House paradiso? My mate, also named Jake, loves it, so mabye you will too, but maybe it was a little too much. It's not exactly the same, but it is really. The thing is with it is that Adrian Edmonson has tried (and failed) to be a more conventional comedy character, and I don't know whether he would be able to do this kind of role anymore, especially when you consider how old they both are.
I'd love to see a Young Ones 20 years later show, and the fact they all died shouldn't matter, because people "died" all the time, or at least had death like things happen to them. One series of Bottom could be good, but I think they wrote one that was too shit for TV and gave up, so perhaps they don't have it in them any more.
