Tickets were supposed to go on sale Monday, April 22, to coincide with Earth Day, but it's been delayed with no explanation.

Woodstock's 50th Anniversary at Watkins Glen is scheduled for August 16-18, and the delay of ticket sales has sparked the question - will there be a concert?. EW is reporting that the festival hasn't even secured the required permits from the NYS Department of Health for the event.

A statement released by Michael Lang, a co-founder of the original festival and producer of the 50th-anniversary edition, dismissed fears of the fest’s cancellation as “just more rumors” in a statement. “Woodstock is a phenomenon that for fifty years has drawn attention to its principles and also the rumors that can be attached to that attention,” Lang said.

Ultimate Classic Rock reports one agent as saying: “No one knows what the hell is going on, but there is clearly a problem.” Speculation includes the suggestion that there could be issues with the venue or investors.

Woodstock 50 will is scheduled to take place Aug. 16-18–the 50th anniversary of the original event almost to the day–in Watkins Glen, N.Y. Some of the original performers from the original Woodstock festival participating are Santana, John Fogerty, David Crosby and more.
