https://vimeo.com/194116649 Steve Martin in conversation, 2002. 34:20 to 36:00 is this exact question. Later, Robin Williams joins him on stage. My cameo starts at 1:01:40, inaudible and off-camera, because I'd traded a seat up close for two in the balcony so my future wife could join me.

Loved the article. Didn't love being blue-balled by the conclusion but still great stuff.

Hard to believe that article doesn't contain the phrase "slide guitar".

I threw together a logarithmic slider for HTML (when I knew little about JavaScript and HTML). I hoped someone would take it and run with it and we would see more logarithmic slide rule calculators on the web.
