Doesn't anyone remember Mos Eisley, from Star Wars? The Tatooine spaceport? Yeah, most kids named this are either children of rabid Star Wars fans or their parents thought they made it up. I doubt it's after this band in most cases.
Yeah, Mos Eisley is totally the first thing I think of. I'm not a rabid Star Wars fan (don't really like sci fi) but my brother was and still is a bit, so I remember. It's a kind of random Star Wars association to pick though... I thought maybe it was supposed to be a variation on Aisley.
