Art,

He showed me one night at the Gate of Horn in the Sixties how to make a glass bottle top slide. We actually broke a whiskey bottle in the catacombs of the Gate with lots of concrete handy. We honed down the sharp edge of the bottle top on the sidewalk outside the club. I think he actually went onstage and did a set with it.

Quite an instruction. Can't learn that in music school.
