And that white death-masklike portrait of Lennon in the center of Olympic Stadium? Pretty ghastly — and especially so when it dissolved (decomposed?) at the end of the song. But that's a separate issue.
Don't get me wrong: Sadly, while I attended many California rock concerts featuring such Lennon contemporaries as the Byrds, Iron Butterfly, B.B. King, Cream and the Rolling Stones, I never saw the Beatles in a live performance.
