LIA via comment to Canceled Grateful Dead and Jerry Garcia Gigs "Possibly this is a misdate for 2/12/66, per the note on a deadlists poster. The Dead may have cancelled both 2/11 and 2/12, or perhaps they weren't scheduled for either date in the first place (they'd left for LA the previous weekend). Is there any evidence? "
runonguinness via comment to Canceled Grateful Dead and Jerry Garcia Gigs "The Dead were definitely originally scheduled for the Fillmore on 66-02-12. There is an earlier version of the Peace Rock poster listing The Mystery Trend, The Quicksilver Messenger Service, Our Lost Souls (The Girls) and The Grateful Dead. The version on deadlists.com has The Wildflower added to the top of the bill and the Dead replaced by Big Brother & The Holding Company at the bottom of the bill, otherwise it is identical. Finally there was a rougher redrawn poster listing The Great Society, The Wildflower, The Quicksilver Messenger Service, Our Lost Souls and Big Brother & The Holding Company with a note at the bottom "... the 'Grateful' are testing, the 'Mystery' lost an ax..." All three posters are for the 12th and make no mention of the 11th. The first and third ones are on page 14 of "The Art Of Rock" by Paul Grushkin [JGMF: verified]. I've never found them online."
