Amazing story.
Many years ago I went to see a show in NYC that was billed as "Fats Domino's Last NYC Live Appearance" It was a super gig.
Near the end Fats said, "I would now like to perform the biggest hit of my career, which was one of my earliest songs and was written by a guy from New York City. Guess what - here I am at the end of my career and I have never once met this man. Would love to thank him."
At that point, Al Lewis, who was sitting just in front of me, leaped to his feet and hollered. "I'm over here Fats."
Al then went on stage, the two of them hugged and cried. Then together they banged out a bunch of hits on the same piano, including of course "Blueberry Hill."
Al Lewis was a multi-talented guy.
