Given your "Two Thumbs Up", I just watched the video again myself.
Three years intervene since that lesson -- and 27 years behind that -- yet every word and demonstration stands.
Interestingly, the only reason the clip made its way to LBG viewers is because the cameraman (and benefactor) -- Collin's Dad, aka "Daddy Cal" -- accidentally left this last tape in my camera (after his own battery had died) prior to his and Collin's return to St. Louis, Missouri. He subsequently gave me permission to use it here.
