There has been some confusion about the date of this performance, but July 4 seems
to be correct. The date is listed in a pre-festival advertisement in the New York
Amsterdam News (June 25); and a review of the festival in Down Beat
(August 11) confirms that the Quintet played on July 4.
The Quintet performed at Chicago's Plugged Nickel Club (July 20-31), then played
in Cleveland at the Ohio Valley Jazz Festival (August 6). They were booked for an
encore in Detroit's Cobo Arena on August 7: "George Wein Presents Festival Encore"
-- scheduled along with the Quintet were Sarah Vaughan, the Dave Brubeck Quartet,
the Horace Silver Quintet, the Jimmy Smith Trio, and Joe Williams. Thanks to Chris
DeVito for this information.
