The Zappa Gig List http://members.shaw.ca/fz-pomd/giglist/1969.html indicates that Zappa played Seattle on 4/19/69, the date confirmed by an ad. There is no listing there for 3/23/69. Unless the show was postponed (possible) it would not be likely for Zappa to play the same city twice in less than a month.
FWIW, there's also a poster out there for Zappa/MOI and the Dead for 6/21/68. It's not in deadlists. It is on the Zappa list but the confirmation is based only on this poster. You can see it at http://gdposters.bravepages.com/1960s/680621.html Iver ----- Original Message ----- From: <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Saturday, January 17, 2004 2:27 PM Subject: new date listing > hi, > i recently came across this poster being sold online.i'd never seen any > listing for this.as of now,no show is listed on this date so it could be correct. > March 23, 1969, Seattle Center Arena > Olympic Mouse productions: The Mothers of Invention, Grateful Dead, Lamb, > Mint Tattoo. > > dave tamarkin > ---------------------------------------------------------------------------- ----
