CNN video(CNN) - The Woodstock 50 festival, which in its planning stages has been plagued by a series of misfortunes and obstacles, will not go on as planned. In April, a marketing firm that was financing the festival opted to pull out, with executives telling festival organizers that they were canceling the event. But organizers, including promoter Lang, one of the creators of the original festival in 1969, said it wasn't up to the firm to cancel the festival, and they trudged on. Last month, festival officials announced that the scheduled venue for Woodstock 50, Watkins Glen International, had pulled out. Artists who performed at the original Woodstock, like Santana and David Crosby, were also set to perform.
