Blue Öyster Cult "A Long Day's Night"

A Long Day's Night is a live DVD by the American hard rock band Blue Öyster Cult, recorded in Chicago, Illinois, on 21 June 2002. It is so named because that day was 2002's summer solstice, the longest day of the year.

The concert was also released on CD, missing seven of the songs included on the DVD-release ("E.T.I.", "Harvester Of Eyes", "Flaming Telepaths", "Last Days Of May", "ME 262", and the encore "Dominance & Submission" and "The Red And The Black"), while the CD-release featured "Astronomy", not available on the DVD.

In 2004, 10 tracks from this concert were released again as Extended Versions: The Encore Collection.
