Our tape dated "6/19/68" is actually from the 2/19/69 Fillmore West show.
There is both musical evidence (the style of Lovelight and Other One clearly places them in early '69, not mid-'68), and written evidence (the events of the show match a Rolling Stone writeup of 2/19/69). Full details here: http://deadessays.blogspot.com/2011/01/mystery-of-61968.html
