DONE4GOOD- Good points you make. I mean I know I've messed up in my life sometimes- but I'd like to think I believe in the greater good of mankind also. Lennon certainly showed that he valued the greater good of mankind through the songs he wrote and what he protested for in standing up to the government at times.
SMIDDY- I looked at the young man with the dark hair in a tux in the lower left hand side of the screen at the 1 minute mark of Lennon's performance of Imagine on this page - I don't believe that was the same guy who killed him about 6 or 7 years later. No, I don't think so. I've seen pictures of the killer Mark David Chapman in the mid 1970's and he was very heavy, rather slovenly and sloppy looking actually with glasses , and had lighter colored brown hair - didn't look anything like this guy you mention here. Can you imagine if Lennon's killer had been stalking him for years and years - how creepy would THAT be ? Gives me the chills just thinking about it. I swear- there are so many psycho's in this world it's pathetic. Thanks for the heads up though. Take care man, Peace out, Mr. Flipper
