Hey, it's not my fault if he's lacking culture...
Perhaps he's in a different culture than you?
If I recall by googling, he made songs in the 60's correct? That's over 50 years ago. I've only heard of his name and the name "space odyssey," but I've not heard one song by him in my life till clicking a link on this thread. Me not hearing a song by him doesn't make me uncultured. His music is old. Not one of my friends ever mentioned his name to me in my life either. Blah.
Like your Starwars example. There's still people who haven't watched it. Yeah it's surprising but I wouldn't say they lack culture.
I'm having a hard time accumulating my words right now but I hope you get my point.
Anyways, rest in peace.
