Pretty amazing that this was even recorded all those many years ago. The really great thing about listening to this, is hearing Lynn ask some of the same questions, and even struggle a bit, with some of the same concepts we "current neophytes" face today. I assume Lynn you gave permission for this to be released, and I for one thank you and whoever provided it for sharing with us.
I infer from something Homer says in the audio that he perceived the book to be more of resource for teachers of the swing rather than students. But with the help of websites like this, it has certainly made me (a student) enjoy golf so much more.
