In 1970, Traffic toured in support of their comeback album "John Barleycorn Must Die", with a quartet line-up of Steve Winwood, Chris Wood, Jim Capaldi, and Ric Grech. In November, the group played a series of concerts at the Fillmore East, and recordings from these concerts were compiled into a live album consisting of "Who Knows What Tomorrow May Bring", "Glad", "Pearly Queen", "40,000 Headmen", "Dear Mr. Fantasy", and "Can't Find My Way Home". This album was set for release in early 1971 but cancelled for unknown reasons, though Side A eventually appeared as bonus tracks on the 1999 reissue of "John Barleycorn Must Die".
