I've heard people say that "all in one place / a generation lost in space" is an obvious reference to Woodstock. Also, "Jack Flash" sounds more like another Jagger reference to me, instead of Kennedy. Though I don't think "dirges in the dark" is an explicit Beatles reference, the marching band refusing to yield and subsequent revelation sounds like a reference to the "bigger than Jesus" brouhaha.
