Who is John Galt and What is John Anderson?

This may be the most lack-luster show to date but people don't head to the John Anderson concert in nowhere Wisconsin unless they are ready to chill and escape the world. I didn't know who John Anderson was before this show and I still am not sure who he is, but it seemed like a lot of people were digging the show. It was a huge change from the Bone Thugs N Harmony concert we partook in at the very same venue the week before but we could use a little rest and relaxation and found it through the smooth melodies of John Anderson.
