Who is this "Joy Division" band, anyway?

Got up this morning to find Chris listening to Alan Cross' "The Ongoing History Of New Music" this morning. I wasn't really listening intently to the bassy rumblings of Mr. Cross until Chris came up to me and we had the following conversation:

Chris: Do you like Joy Division?
Me: Well, yes... I like them very much.
Chris: Oh. I hadn't actually heard them before. You know, I always thought their name was kinda stupid -- until I found out what it meant.
Me: Yeah. Creepy now, isn't it?
(pause)
Me: So do you now know that they ultimately spawned New Order?
Chris: What? How could they? Their lead singer died.
Me (fighting back a smirk that comes with imagining Ian Curtis singing jauntily, "Up, down, turn around, please don't let me hit the ground"): You know, if you had just watched 24 Hour Party People with me when it was on TV, you would know all this.
Chris: Yeah, well. It's one thing to actually watch it. It's another to just have it going on in the background, which is what I prefer.


Sigh.
