I purchased this book after buying the Elton John Piano Solos book. (I play from the Elton John book at least once a day, and it has given me so much enjoyment.) I was expecting the same type of arrangements with this one, but I was very disappointed to discover that none of these piano solos sound anything like the recorded versions of Billy Joel's songs. In the Elton John book, songs are written in the original keys and the arrangements are complex and rich-sounding. In this book, the arrangements are in different keys, simplified, and just plain flat. Not one song in this book justified my purchase to be honest.
