If you're a BBC fan have a listen to Alexi Sayle reminisce about the 'good old days', it's sadly not what it used to be... https://audioboom.com/channels/5038428

The Young Ones inveigled its way into my psyche growing up and I'm sure I'd be a different person if I hadn't watched and rewatched it. Incredibly of-its-time-UK 80s now, but wild nonetheless. There's a low-quality VHS rip on the 'net somewhere of the frantic production process of the show which is both slightly enchantment-breaking and fascinating. They did so many takes of the circular-saw-through-the-bed gag due to technical issues! Without the laugh track production all sounds rather stressful for everyone, but also shows how much in-house BBC known-how was involved in the production.
