iPad For Musicians. How to make a "living set list" using Keynote.

I've used an iPad to control a PA system and I have used Keynote to create live show visuals, but it never dawned on me that I could use both of those things to create a dynamic set list.
This video gives a brief walk thru of how I use Keynote to make a set list that adds all the information I need (including lyrics) to a variety of different ever evolving set lists.
Using the iPad as my set list has helped bring my stress level down at shows and encouraged me to try things much sooner than I normally would have. And as a result it's allowed me to add new material to my concerts much more frequently.
Hope this helps some of you out there, who like me, had never seen this application before.
