I was sad to hear this yesterday afternoon.
As a teenager, in the 80's, watching The Young Ones was the equivalent to punk TV. Its was anti-establishment as opposed to the normal sit-com/saturday night variety comedy that went before. I loved it, my parents didn't get it.
I watched the Comic Strip series, then Filthy Rich & Catflap, Bottom. All 'utterly brrrilliant'. Early stuff like Dangerous Brothers was great and my all time fave 'Mr Jolly Lives Next Door'
Rik will be sorely missed by a generation who grew up to the alternative comedy scene and knowing that, no matter what, Rik & Ade will never perform together again is a great loss.
