But physical evidence is never produced is it?
I did hear of one chap who had actual photographic proof that Elvis was still alive.
He contacted a newspaper and they sent a journalist out. It was a remote cottage near a country trail. The chap told the story about how he was sitting outside and saw a stranger walk by, realised it was Elvis and called out to him, and chatted for a while before asking for the photograph. So the journo finally asks to see the picture. It showed the man, standing next to his cottage with a copy of a recent newspaper. "Where's Elvis?" asks the journo. "Who do you think took the photo?" says the chap.
