Along the lines of world peace and unity, Rocker T offers a great guitar lesson a number of years ago to friends at the Rainbow Gathering in 2003.
Thanks, Zev, for uploading this beautiful video.
Kind of makes you want to read more carefully the side of a Dr. Bronner's bottle of Castille soap. Just a point of interest that the Bronner family were originally German Jews. The family name was Heilbronner, and the "Heil' part was dropped as Hitler rose to power. The reggae connection is for sure there!
