Mike:
Thanks for remembering! I had forgotten about that particular incident until you brought it up. It took place following a talk he did in San Francisco promoting his then newly published memoir Searching for the Sound (a great read, by the way) But, to set the record straight, it was someone else who accosted Mr. Lesh literally while he was standing using the urinal. I, on the other hand, started up my conversation while we were both washing our hands at the sinks after doing our respective business.
