I don't think you offended anyone with your sense of humour! Don't worry!
I think that everyone would be very happy if Elvis would be alive and if he could talk with us about his music and about his life...and about his death. And yes, he could die (again), but this time because of his old age.
But you would forgive him for not telling us for such o long time that he was alive? Our world is a little less beautiful without him!
