If you can sit through the opening ramble, there is actually some information on hammers in here somewhere.
One thing I forgot to do is credit the music. The opening is "Goodbye Again" by Dave Alvin with Rosie Flores, off "King of California", one of my favorite albums of all time. At the end I've tacked on Steve Earle's "Home to Houston" off of "The Revolution Starts Now."
It's probably not entirely legal to use this stuff, but I just can't help myself from evangelizing. I sincerely believe that if you hear it, you will be hooked, go to Itunes or whatever, and buy it.
