I was cleaning up some programs that I am not likely to use on my new MacBook Air (iPhoto, iMovie), and I figured I would also blow away Garage Band. 

Before I deleted it, I thought I would open it up and see what it was all about. Then I found the Lessons part.

Damn, that is cool.  Really cool. Now I need to buy widget to get my guitar plugged into my Mac.

I bought the Artist Lesson of Alex Lifeson teaching how to play Working Man. 

Damn, I am going to waste a lot of time with this.
