This piece is a gem... It has been passed along person to person for over 20 years. From tape to tape and then to CD so there is some hissing in the background. I recommend passing it along, but knowing the right moment and person/group to pass it to is important... don't over play it... wait for it to call you to listen to it... As far as I know it has always been passed for free and without credits... Use it wisely. I post this here today because there is someone that needs to hear it. Enjoy...
