Hi, thanks for the quick reply.

I have the Johnson book, and it's very helpful. I started out with this one http://www.halleonard.com/product/vi...?itemid=695867, which provided a great introduction to this style.

I agree that it's best to memorize the chords to be able to play them on the fly. I'm just looking for a crutch to help ease that process ;-) Is there a way to add my own chord diagrams?

I'm a singer (from a rock background), so I suppose I get to control what keys songs are playing in anyway, right?
