As a child, he was a shabbos goy for a rabbi neighbor. As an adult, he donated to Jewish charities. He even wore a Chai necklace (sometimes paired with a cross), saying "I don't want to miss out on going to heaven on a technicality." (Of course, if he really was Jewish, he'd know that our concept of heaven quite differs from the Christian one. But can't blame a guy for trying.)
And you can't blame us for wanting Elvis on our team. We certainly would prefer him to that OTHER Jew known as "The King", right?
(Editor's update: We're fully aware of claims and even "proof" that Elvis had Jewish lineage. However, actual genealogical research has shown otherwise. So, Not a Jew.)
