Yes, proven false. I contacted WV when they first started streaming it. I told them that there was a complete performance, sent them a copy to prove it but they didn't care. They confirmed that it was the same recording (obvious to anyone that's heard both) but all WV cared about is that they legally licensed it from Bill Graham's collection. Not that Bill ever owned the rights to it to begin with. It was just a copy of Reinhart's recording in his collection and no one ever challenged it.This is from Wolfgang's website. Has it been provedn false?
"The first night, May 9, 1977, is often considered to be one of the greatest performances of the band's career. The band members seemed to enjoy the show just as much as their rapt audience"
"Bill Graham's partial soundboard recording of this legendary performance begins near the end of the first set, approximately eight minutes into the final sequence of "Pigs (Three Different Ones)." The piece is relaxed but focused, with Rick Wright's spooky synth and one of the band's heavier jams highlighting this set-ending performance"
