Volgens Iron Butterfly heeft onze Jap gelijk hoor:
Iron Butterfly, which pioneered heavy metal rock'n'roll, was also scheduled to play. The group arrived in New York from a seven-week, nationwide tour and called for a helicopter to bring it to the festival. But Lang and the other organizers worried that Iron Butterfly's brand of hippie/heavy-metal music might be dangerous under the circumstances. Emcee John Morris dispatched a nasty telegram to the group at the airport. It was designed to provoke the members into deciding not to play. But Lee Dorman, Iron Butterfly's bassist, remembers it differently. Woodstock organizers, he said, were supposed to send a helicopter and didn't.
