If one zooms in on the map to Kezar stadium you give several links to the 1973-05-26 Dead concert. These are all labeled "Fan Tape." I thought, "Wow," because the only actual tape made by a fan known to exist is mine which is used to patch the soundboard to make the collectable complete version of this concert for Dead collectors (shnid 83535). So I listen to Row Jimmy on all 5 versions of "Fan Tapes" you link. They're all the same Bettyboard with the gap at 3:31. Questions: Is it your convention to list Dead soundboards as "Fan Tapes?" Why list the same one so many times? Coincidence: I received one of the first graduate degrees ever awarded by UCSC; MA in History in 1972, a year before I recorded this concert. So I used my UCSC education well! Regards, Gene Taback
