Shown are three inconsecutive video frames from the original 1/2" reel to reel 1971 videotape of the first half hour of the afternoon show two events held on August 1, 1971 of the Concert for Bangla Desh at Madison Square Garden, New York City. The videotape was recorded by author, historian, archivist and filmmaker / video producer Richard Warren Lipack.
