I was just coming in here to mention this one. I grew up with my mom always listening to the oldies stations. So this soundtrack is nostalgia overload for me.
I live in Nebraska and have never witnessed a person drink Keystone. However, when I go cycling I do see them littered on the sides of the highway along with Fireball shooters. So, I think that speaks to the demographic.
I'm a big Buster Keaton fan and I think most of his movies are still great. The General (minus the wrong side of the Civil War), Steamboat Bill Jr, and One Week in particular.
