Release date to be removed from a title...

An unbroadcast pilot for a US adaptation of The Young Ones, this was due to originally air in 1990. However, low ratings for a season of pilots saw it pulled from broadcast.

This is quite extensively covered on star Nigel Planer's Patreon (which is behind a paywall, but I've joined and uploaded screenshots twice): https://www.patreon.com/c/NigelPlaner  

As the articles state, the most compelling evidence that it WASN'T shown was the fact that 1990 was well within the video age and this hasn't been leaked in 36 years.

It's just been uploaded to Planer's Patreon, so I was able to complete full details. Despite submitting a deletion for the 1990 date on two separate instances, it hasn't been accepted.
