When we went to Phil Spector's house in the 70s he came to the door holding a bottle of diet Manischewitz wine in one hand and a presumably loaded 45 automatic in the other. Long story. I thought he was nuts.

The Ramones story I remember was that when they were recording he'd be in the control room with the lights off so they couldn't see him and sometimes he'd just leave without telling them and they'd just be standing there

Ok this is part of the story. He was working on the Cohen album and played it for us. But he played it absurdly loud so it just sounded like distorted crap and the A&R guy with us jokingly whispers to me "play your cards right and you could sound liked this" https://twitter.com/craigmcneilly/status/1350860063477530624
