Hey Stephen! I am taking the liberty of posting this at the KCAC Lives! blog so it can be shared. This little blog by the way has had something like 600 serious readers this month!
To answer your question; the song you refer to is by The Incredible String Band from `The Hangman's Beautiful Daughter' and is part III of "A Very Cellular Song". I can think of no song that was more definitive of the spirit of KCAC than that one. The first time I really HEARD it, I was alone, listening in monaural, baking in a little house in Sunnyslope. The experience wasn't "gee-my hair stood on end" or anything like "oh goodness my skin prickled". For me it was a soul-shaking electrifying experience almost like sticking one's finger in a light socket.
I have to say if you experienced anything like that remotely - and in fact you REMEMBER it, you can can count yourself among The Chosen. THAT is the essence and charisma of KCAC, now in (at least) its third incarnation at radiofreephoenix.com
PS... For almost any song you can think of, check out Limewire.
Thank You Ron, for getting back to me so quickly.
My experience of this song was simple and profound. I was tuned in every day prior to sunset, feeling the end of daylight as this song comforted me. The experience had few words. Feeling warm and hopeful, something moved inside me in a deep personal place. I was prepared for the coming night with a sense of gratitude.
I am off now to try and find the piece of music. Thank you again. I look forward to perusing.
NOTES: Stephen connected with the WHOLE album!
