The creativity of Irving Berlin was amazing. This is a story of an interesting life, but also points out that, eventually, time erases foundations just like eroding soil or dripping water. Now, I would like to find a source to hear all of his songs as his number one concern was always quality. At times he would create a song in minutes, but it could also take years. As with most artists, he was continually looking for verification that his output was good. The appendix lists ALL of his tunes as well as other interesting data. A fine read.
