We saw Paul Sinha at The Stand (in Glasgow) a few months ago, probably doing the same act mentioned above, and we really enjoyed it! There was a queue of people afterwards waiting to meet him, but my partner just "photobombed" and left.
I've found PS very personable and likeable on a few podcasts he's been interviewed on in recent years, too.
As for Rik and Ade - I was bloody obsessed with The Young Ones and I had Betamax (!) videos of it on repeat in my youth - whereas my sister watched Grease (the first movie) non-stop - when we got the chance.
Bottom*, I liked, up to a point, but it really got tired and dull towards the end (Guest House Paradiso I've tried to watch but it actually puts this insomniac to sleep).
However, I do think Rik could have made his name following someone like Steve Coogan's career path - there was definitely more mileage in Alan B'Stard. Not sure why that didn't really progress.
I was going to buy Ade's autobiography but nobody wants to know about the pre-fame stuff, particularly if it's the majority of the book. Disappointing.
I think it was hinted at that Rik's personality changed somewhat after his head injury and health issues, which isn't really surprising. And he found it harder to memorise his lines, which is a bit sad. Rik was very lovable and the slapstick, although it had its day, was only the tip of the iceberg of his talents. He died far too soon.
(I have a picture of my late-teen brothers doing the "nazi salute" when Rik did book signings for "Bigger Than Hitler, Better Than Christ" - unfortunately, as it's written "in character" and didn't get great reviews I didn't buy that autobiog either - but it was the "thing" Rik did at these public appearances. If you were a bit older, he'd usually pose pretending to give you a "blowjob". The proof of these photos was searchable on Flickr, though I'm not seeing any nowadays).
*I'm sure there's a tasteless joke about me preferring Young Ones to Bottom - !!
