The Atlantic City Pop Festival took place in 1969 on August 1, 2 and 3rd at the Atlantic City race track, two weeks before the better known Woodstock Festival. The festival is often confused with the Atlanta International Pop Festival (1969), which took place over the 1969 Fourth of July weekend.
Attended by some 100,000+ people, the festival featured the following performers (partial list):
Biff Rose was the master of ceremonies. Rose filled in for Joni Mitchell when she started to cry and ran off stage in the middle of her 3rd song because the crowd was not paying attention to her performance. It seems she was placed in the rotation directly after Mother Earth featuring Tracy Nelson and the crowd wasn't ready to hear her mild act.
Crosby, Stills & Nash were originally on the lineup but ended up as a no-show, Nash supposedly had polyps on tonsils (but sang at Woodstock two weeks later). The Chambers Brothers were a last-minute substitute.
The Moody Blues were scheduled but weren't there.
Johnny Winter was present but did not perform as his equipment did not show up in time.
