AI Slop 79: Grandad's Mellow 1970s Prog Rock On Tinny AM Radio

Your 75 year old grandfather smoked wicked hash and sometimes Thai Stick, impregnated with opium, while listening to music like this back in the 1970s.
Well, not this. Better stuff than this. Still, it does stick in the head after a few listens, like something you might have heard at a funeral wake a few times in one afternoon and then you're humming it a few days later before suddenly stopping because you remembered you heard it at a funeral.
