I bought this book a few years ago from the Getty's website. I love it! I sing these songs in church frequently and get requests for them. The music is easy. I have no problem playing and singing them at the same time. You may want to improvise some, but I don't much because I want to focus on the message within the song. I also have the 'Awaken the Dawn' book and it is just as good.
This book has been on my wife's wishlist for too long. We really appreciate the songwriting of Keith Getty. Wonderful lyrics that express praise to the Lord and melodies that are beautiful to sing. Now we can learn them and enjoy them together.
