Thanks so much for your help!!! I'm so glad you had the time to
respond to my newbie question.

And as if you read my mind as I was going through the SICP lecture and
referencing chapter two in Manning's Joy of Clojure book I was
wondering how to turn this explicit recursive call taken from the
scheme example into a Clojure non-tail recursion using 'recur'. I had
been unsuccessful in my trials, so thank you times two!!!

I'm off to try this out in my REPL!

Many bows,
Joshua
