David, thanks for your insightful post. I love reading about the working of the minds of such good writers. I love the inspirational part of writing and then struggle with then organizational part, the structure. I love reading the Pat Pattisons, Robin Fredricks, etc. but only take away so much. I think Floyd loves the mathmatics of writing more than me for sure, setting up these catchy hooks.
Anyway, enjoyable read and fine job on this song.

Kenny
