That's quite a bizarre thing to say, BC. Did Johnny Cash REALLY kill a man in Reno just to watch him die? Did Janis Joplin REALLY buy a Mercedes-Benz? Did Tom Paxton REALLY go to the zoo the day after he wrote the song? Did Peggy Seeger really get her engineering degree from MIT? And most painfully, did Woody Guthrie really wrap himself in paper and put himself through the U.S. Mail service?Easy answer: No.
And who says Lee wrote the song? He most probably DIDN'T.
