It’s true. July or August of 1968, Auditorium Theatre. The clincher for me was that The Soft Machine opened: http://www.youtube.com/watch?v=Mwo3ht8sxJo&feature=related (I already had their LP). All this came flooding back (and yes, I do remember the ’60s) when I came across this record of a vibrant performance.
