Umlaut started going to concerts in the late-70's around the S.F. Bay Area and over the years and hundreds (and hundreds.. and hundreds..) of shows I came to recognize some BGP staffers.. They became part of all those shows for me from seeing them at all those venues; I never knew his name, but Art was one of those BGP Bluecoats who I saw at seemingly every concert I attended.
Rest In Peace Art Abuse. There will be a memorial concert for him on March 23rd at the Great American Music Hall featuring Steve Earle.

Thanks to Lauraloha for passing this along. Cue 'Greensleeves'.
For the newbies: Bill Graham would play 'Greensleeves' as the houselights came up at shows to let the crowds know the show was officially over.
