I remember watching this with my dad when it was on telly one night in the mid-80s or maybe a little later. Didn't have much of a clue what was going on and I've never had any interest in rewatching it (also had no idea it was a beloved cult classic rather than a weird curio) but there are definitely scenes or images from it seared into my memory. "Fiddle about" being one and some sort of toilet seat covered in toothpicks another.
Quadrophenia next?
